NL230
High Energy Q-switched DPSS Nd:YAG Lasers
The NL230 series diode-pumped short nanosecond lasers are designed to produce high-intensity, high-brightness pulses and are targeted for applications such as material ablation, Light Detection And Ranging (LIDAR), remote sensing, mass spectroscopy, OPO, Ti:Sapphire or dye laser pumping and many more.

- Due to continuous improvement, all specifications are subject to change. The parameters marked typical may vary with each unit we manufacture. Unless stated otherwise all specifications are measured at 1064 nm and for basic system without options.
- Outputs are not simultaneous. Inquire for higher energy (up to 350 mJ at 50 Hz, 250 mJ at 100 Hz) custom models.
- Averaged from pulses, emitted during 30 sec time interval.
- Measured over 8 hours period after 20 min warm-up when ambient temperature variation is less than ± 2 °C and humidity <± 5%.
- FWHM.
- Near field (at the output aperture) TOP HAT fit is >80%.
- Full angle measured at the 1/e2 level.
- Beam pointing stability is evaluated as movement of the beam centroid in the focal plane of a focusing element.
- Beam diameter is measured at 1064 nm at the 1/e2 level.
- Adequate room air conditioning should be provided.
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.
