NL200 Series - Diode-pumped Actively Q-switched Nd:YAG Lasers

The actively Q-switched NL200 series is a very compact air-cooled DPSS laser design. The fiber-coupled pump light avoids heat influence to the resonators which results in very stable and maintenance-free laser operation. The laser features variable repetition rates of up to 2500 Hz, short pulse lengths of 7 - 10 ns and pulse energy of up to 4 mJ.

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, 266 nm and 213 nm wavelengths are 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 make 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.
