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.
