Ekspla NT242 series nanosecond tunable DPSS lasers

NT242 series tunable wavelength lasers 1

Ekspla's NT242 series lasers produce pulses at an unprecedented 1 kHz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact housing, the diode pumped Q-switched Nd:YAG laser and OPO offers hands‑free, no-gap tuning from 210 to 2600 nm. With its 1000 Hz repetition rate, the NT242 series laser establishes itself as a versatile tool for many laboratory applications, including laser induced fluorescence, flash photolysis, photobiology, metrology, remote sensing, etc.

NT242 series systems can be controlled from a user-friendly remote control pad or/and a computer using supplied LabVIEW™ drivers. The control pad allows easy control of all parameters and features on a backlit display that is easy to read even with laser safety eyewear. Thanks to a DPSS pump source, the laser requires little maintenance. It is cooled by a stand alone chiller, which further reduces running costs. A built‑in OPO pump energy monitor allows monitoring of pump laser performance without the use of external power meters. A standard feature includes a separate output port for the 355 nm pump beam.

Ekspla NT200 series Tunable Wavelength NIR-IR Range DPSS Lasers

nt200 series laser 1

Ekspla's NT200 series tunable laser systems integrates into a single compact housing a nanosecond Optical Parametric Oscillator (OPO) and Diode-Pumped Solid–State (DPSS) Q-switched pump laser. Diode pumping enables fast data acquisition at high pulse repetition rates up to 10 kHz (depending on model) while avoiding frequent flashlamp changes that are common when flashlamp pumped lasers are used. Most of the pump lasers do not require water for cooling, thus further reducing running and maintenance costs.

All lasers feature motorized tuning across the specified tuning range. The output wavelength can be set from control pad with backlit display that is easy to read even while wearing laser safety glasses. Alternatively, the laser can be controlled also from personal computer through USB (RS-232 is optional) interface using supplied LabVIEW™ drivers. High conversion efficiency, stable output, easy maintenance and compact size make our systems excellent choice for many applications. Read more.

Ekspla NL940 Series High Energy Temporary Shaped Nanosecond Nd:YAG Lasers

NL940 series nanosecond NdYAG laser

The Ekspla NL940 series main laser feature is output of temporary shaped pulses based on electrooptical modulator driven by programable arbitrary form generator (AWG). Pulse shaping resolution is 125 ps, while maximum pulse length is 10 ns. Start of the system is single mode CW laser. Then light is amplified in fibre amplifier, later AWG driven modulator transmits only required temporal shape and duration pulse which is amplified in diode pumped regenerative amplifier in order to reach energy sufficient to amplify in singly pass flash-lamp pumped amplifiers.

Power amplifier is a chain of single-pass amplifiers where pulse is amplified up to required energy. During amplification spatial beam shaping is emloyed in order to get flat top shape at the output. The second harmonic generator is based on angle tuned nonlinear crystal placed in a heater. Read more.

Ekspla NL120 Series SLM Q-switched Nd:YAG Lasers

NL120 series high energy SLM Q switched NdYAG lasers 1

Ekspla's  NL120 series electro-optically Q-switched nanosecond Nd:YAG lasers deliver up to 10 J per pulse with excellent stability. The innovative, diode‑pumped, self‑seeded master oscillator design results in Single Longitudinal Mode (SLM) output without the use of external expensive narrow linewidth seed diodes and cavity‑locking electronics. Unlike more common designs that use an unstable laser cavity, the stable master oscillator cavity produces a TEM₀₀ spatial mode output that results in excellent beam properties after the amplification stages.

NL120 series Q-switched nanosecond lasers are an excellent choice for many applications, including OPO, OPCPA or dye laser pumping, holography, LIF spectroscopy, remote sensing, optics testing and other tasks. For tasks that require a smooth and as close as possible to the Gaussian beam profile, models with improved Gaussian fit are available).

The low jitter of the optical pulse with respect to the Q-switch triggering pulse allows the reliable synchronization between the laser and external equipment. The optional second (SH) (for 532 nm), third (TH) (for 355 nm) and fourth (FH) (for 266 nm) harmonics generators provide access to shorter wavelengths.

The laser is controlled by a supplied netbook PC via USB port with application for Windows™ operating system. In addition, the main settings of the laser can be controlled through an auxiliary user-friendly remote control pad. The remote pad features a backlit display that is easy to read even when wearing laser safety eyewear. Read More.
