• 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.

  • Ekspla PGx03 Picosecond kHz Repetition Rate Broadly Tunable OPA

    PGX03 series kHz repetition rate picosecond OPG

    Ekspla's PGx03 series Optical Parametric Generators (OPG) are designed to be pumped by 1 kHz mode-locked lasers with 1 W average power. An excellent choice is the PL2210A series mode‑locked picosecond laser from EKSPLA.

    The optical design is optimized to produce low divergence beams with moderate linewidth (typically 12 cm⁻¹) at approximately 20 ps pulse duration. Due to the unique broad tunability range from 210 to 16000 nm these devices are an excellent choice for many spectroscopic applications.

    Upon request the optical layout can be easily modified for pumping by other mode-locked lasers with high pulse energy or longer pulse duration.

    Microprocessor based control system provides automatic positioning of relevant components for hands free operation. Nonlinear crystals, diffraction grating and filters are rotated by ultra-precise stepper motors in the microstepping mode, with excellent reproducibility.

    Precise nonlinear crystal temperature stabilization ensures long-term stability of generated wavelength and output power.

    For customer convenience the system can be controlled using a user-friendly remote control pad or through USB interface (RS232 is optional) from a personal computer (PC) using supplied LabVIEW™ drivers.

  • 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). SOPO is pumped by a train of pulses at approx. 87 MHz pulse repetition rate. The output from SOPO consists of a train of pulses with excellent spatial and spectral characteristics, determined by the SOPO cavity parameters.

    OPA is pumped by a single pulse temporally overlapped with SOPO output. After amplification at SOPO resonating wavelength, the PGx11 output represents a high intensity single pulse on top of a low-intensity train, while in all other spectral ranges (idler for PG411 and PG711, signal for PG511, also DFG stages) only a single high intensity pulse is present.

    Microprocessor based control system provides automatic positioning of relevant components, allowing hands free operation. Nonlinear crystals, diffraction grating and filters are rotated by ultra-precise stepper motors in microstepping mode, with excellent reproducibility.

    Precise nonlinear crystal temperature stabilization ensures long-term stability of generated wavelength and output power.

    For customer convenience the system can be controlled using a user-friendly remote control pad or through USB interface (RS232 is optional) from a personal computer (PC) using supplied LabView™ drivers.

Applications include infrared spectroscopy and vibrational spectroscopy on surfaces.

    All models produce nearly diffraction limited divergence beams, with M² measured as <1.3 over the tuning range.

    The microprocessor-controlled wavelength tuning is fully automatic. The wavelength controlling elements are mounted on precise micro‑stepping motors. The temperature of the non‑linear crystal is controlled by a precise thermocontroller with a bidirectional Peltier element, resulting in the fast tuning of crystal temperature. The lasers may be controlled from a remote keypad or via USB (RS232 is optional) interface from a personal computer using LabView™ drivers. Read more
