  • Ekspla CARS Microspectrometer

    Coherent Anti Stokes Raman Scattering Microspectrometer

    Coherent anti-Stokes Raman scattering (CARS) spectroscopy primarily was used in chemistry, physics and related fields. It is sensitive to the same vibrational signatures of molecules as seen in Raman spectroscopy, typically the nuclear vibrations of chemical bonds. Unlike Raman spectroscopy, CARS employs multiple photons to address the molecular vibrations, and produces a signal in which the emitted waves are coherent with one another. As a result, CARS is orders of magnitude stronger than spontaneous Raman emission. CARS is a third-order nonlinear optical process involving three laser beams: a pump beam of frequency ω pump , a Stokes beam of frequency ω Stokes and a probe beam at frequency ω probe. Read more.

  • Ekspla SFG Spectrometer Sum Frequency Generation (SFG) Vibrational Spectrometer

    sfg spectrometer

    The Ekspla Sum frequency generation (SFG) spectrometer is based on picosecond pump laser and optical parametric generator (OPG) with difference frequency generation (DFG) extension. Solid state mode-locked Nd:YAG laser featuring high pulse duration and energy stability is used in the system. Fundamental laser radiation splits into several channels in multichannel beams delivery unit. Two of these beams are used for pumping OPG and DFG. Small part of laser output beam, usually with doubled frequency (532 nm), is directed to VIS channel of SFG spectrometer. IR channel of spectrometer is pumped by DFG output beam. All system components are designed to operate in tandem. The sizes of individual compartments, positions of apertures and beams heights are fitted. As a result SFG spectrometer takes less space in laboratory. Standard versions usually fit on 1000×2400 mm optical table. No laser beams are passing across optical table. For example beam dedicated for VIS channel passes through OPG compartment only to minimize the risk of accident with dangerous high intensity laser radiation. It makes Ekspla spectrometer substantially safer comparing to home-made SFG-VS setups. Also optical parameters, like beam diameter, pulse energy, delays between channels are perfectly matched. We designed our spectrometer thinking about user friendly operation. Read more.

  • Ekspla SL212 Series SBS Compressed Picosecond Nd:YAG Lasers

    SL212 series SBS compressed Q switched NdYAG Laser 1

    Ekspla's  SL212 laser is excellent solution for applications, where high energy picosecond pulses are needed. In contrary to conventional mode-locked lasers the SL212 series lasers use different method of generating short pulses based on backward-stimulated Brillouin scattering (SBS). Diode pumped passive Q-switched single longitudinal mode (SLM) nanosecond generator is the heart of the system. It provides nanosecond optical pulse that is later compressed during SBS in a special cell.

    Pulse compressor consists of optical guiding system and SBS-cell. SBS cell is designed for safe and longlife maintenance free operation. A linearly polarized light pulse from master oscillator passes through QWP and is focused into SBS-cell by lens. Focusing is arranged in the way to compress the pulse via SBS process. The backscattered Stokes pulse, as its phase is reversed, strictly repeats the path of pump pulse in the opposite direction and with a reversal divergence. The compressed pulse is guided into the amplification stage using polarizer and mirror.

    After SBS compression, pulse is directed to multi-pass flashlamp pumped power amplifier system, providing high-energy pulses. SL212 model lasers use multi-pass amplifier system which is based on laser chamber containing Nd:YAG rod pumped by two flash lamps. For smooth obtaining output beam profile pre-amplifier and double-pass amplifier layout is used in SL212 series lasers. Power amplifier includes optical components arranging passes through the active element. Aperture is employed to prevent the returning depolarized radiation from getting back into the amplifier.

    Thermocontrolled harmonics’ generators, based on angle-tuned non-linear crystals and harmonic separation optics are available as standard options. Fundamental and second harmonics are separated and has a single output port. Harmonics’ crystals mounted in temperature‑controlled heaters. Pulse compression during SBS, is a simple and cost effective way for generating high power picosecond pulses. In addition to it, SBS compression allows generation of pulses with exceptional pulse duration range: from 150 ps up to 1000 ps. A power supply and water/water type cooling units, placed in standard 19” rack, requires a little space under the user’s optical table. Read more.

  • Ekspla PGx11 Transform Limited Broadly Tunable Picosecond OPA

    PGX11 series picosecond narrow linewidth OPG

    Ekspla's PGx11 series optical parametric devices employ advanced design concepts in order to produce broadly tunable picosecond pulses with nearly Fourier-transform limited linewidth and low divergence. High brightness output beam makes the PGx11 series units an excellent choice for advanced spectroscopy applications.

    Optical layout of PGx11 units consists of Synchronously pumped Optical Parametric Oscillator (SOPO) and Optical Parametric Amplifier (OPA).

  • Ekspla SL330 Series SBS Compressed Picosecond Nd:YAG Lasers

    Picosecond SBS compressed high energy NdYAG lasers SL330 series 2

    Ekspla's SL300 series lasersare an excellent solution for applications that require high energy picosecond pulses. Pulse compression during backward‑stimulated Brillouin scattering (SBS), used in EKSPLA SL300 series lasers, is a simple and cost‑efficient way to generate picosecond pulses, with the unique capability of producing pulses with tunable duration.

    An electro-optically Q-switched Single Longitudinal Mode (SLM) nanosecond generator is the heart of the system. Instead of external narrow linewidth diode lasers, the selective properties of Fabry-Perrot etalon, and a laser cavity are used to produce SLM pulses with a smooth temporal envelope. In scientific literature this method of generating SLM pulses is known as a selfseeding technique.

    Pulse compression is done in a SBS‑cell. Depending on the geometry of interaction, a pulse with duration in the 170 – 1500 ps range can be produced. Pulse duration can be tuned in discrete steps when a variable pulse duration option (-VPx) is installed. After SBS compression, the pulse is directed to a multi-pass power amplifier system for amplification to up to 500 mJ energy.

    Temperature controlled harmonics generators, based on angle-tuned KD*P and KDP crystals and harmonic separation optics, are available as standard options. Each wavelength has a separate output port.

    A power supply and cooling units are placed in a standard 19” rack that requires little space under an optical table. The very low jitter of the optical pulse relative to the Q-switch triggering pulse ensures reliable synchronization of the laser with external equipment. For customer convenience the laser can be controlled from a user-friendly remote control pad or RS232 interface. The remote pad allows easy control of all laser parameters and features a backlit display that is easy to read even when wearing laser safety eyewear. Alternatively, the laser can be controlled from a personal computer with supplied software for a Windows™ operating system. LabView™ drivers are supplied as well. Read more

  • Ekspla PGx01 series: High Energy Broadly Tunable Picosecond OPA

    PGx01 series picosecond high peak power OPG

    Travelling Wave Optical Parametric Generators (TWOPG) are an excellent choice for researchers who need an ultra‑fast tunable coherent light source from UV to mid IR.

    The purpose of the OPG module is to generate parametric superfluores-cence (PS). Spectral properties of the PS are determined by the properties of a nonlinear crystal and usually vary with the generated wavelength.

    In order to produce narrowband radiation, the output from OPG is narrowed by LNS down to 6 cm⁻¹ and then used to seed OPA.

    Output wavelength tuning is achieved by changing the angle of the nonlinear crystal(s) and grating. To ensure exceptional wavelength reproducibility, computerized control unit driven precise stepper motors rotate the nonlinear crystals and diffraction grating. Nonlinear crystal temperature stabilization ensures long‑term stability of the output radiation wavelength.

    In order to protect nonlinear crystals from damage, the pump pulse energy is monitored by built-in photodetectors, and the control unit produces an alert signal when pump pulse energy exceeds the preset value.

    For customer convenience the system can be controlled through its USB type PC interface (RS232 is optional) with LabView™ drivers or a user-friendly remote control pad. Both options allow easy control of system settings. Read more.
