NL200 series DPSS Q-switched nanosecond lasers offer high pulse energy at kHz repetition rates. End-pumped design makes this laser compact and easy to integrate. Harmonic generation modules for 532 nm, 355 nm and 266 nm wavelengths can be combined into one module, easily attached to the laser frame.
Featuring short pulse duration, variable repetition rate and external TTL triggering, nanosecond diode pumped NL200 series Q-switched lasers are excellent cost effective sources for specific applications like pulsed laser deposition, ablation through mask or intravolume marking of transparent materials, when higher pulse energy is required. Excellent energy stability and a wide range of wavelength options makes this laser a perfect tool for spectroscopy and remote sensing applications.
Mechanically stable and hermetically sealed design ensures reliable operation and long lifetime of laser components.
