Description
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.

- Due to continuous improvement, all specifications are subject to change. Parameters marked typical are illustrative; they are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise all specifications are measured at 1064 nm and for basic system without options.
- Unless stated otherwise all specifications are measured at 2500 Hz pulse repetition rate.
- Unless stated otherwise all specifications are measured at 1000 Hz pulse repetition rate.
- Averaged from pulses emitted during 30 sec time interval.
- FWHM at 1064 nm.
- Measured over 8 hour period after 20 min warm-up when ambient temperature variation is less than ±2 °C.
- Full angle measured at the 1/e² level at 1064 nm.
- Beam diameter is measured at 1064 nm at the 1/e² level.
- Beam pointing stability is evaluated as movement of the beam centroid in the focal plane of a focusing element.
- With respect to QSW IN or SYNC OUT pulse.
- Without optional harmonics module.
Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
