Description

NL200 series DPSS air-cooled nanosecond lasers offer high pulse energy at kHz repetition rates. End-pumped design makes this laser compact and easy to integrate into various laser equipment both industrial and R&D. Featuring short nanosecond pulse duration, variable repetition rate and external TTL triggering, nanosecond diode pumped NL200 series Q-switched lasers are excellent and cost-effective sources for specific applications, when higher pulse energy is required, like material processing, LCD and OLED display panel repair, ablation, marking, engraving, laser cleaning, laser deposition and many more.

This laser can be equipped with harmonic generation modules for 532 nm, 355 nm, 266 nm and 213 nm wavelengths. Excellent energy stability and a wide range of wavelength options make this laser a perfect tool for spectroscopy, photoacoustic imaging and remote sensing applications. The mechanically stable and hermetically sealed design ensures reliable operation and long lifetime of the laser components.

Because of its robust design and diode-pumped technology this laser can work 24/7 with minimal down time and low ownership cost.

  1. Please indicate clearly if 1064 nm output is required in case harmonics options are ordered (except H200STHC module). In such a case, the energy of 1064 nm is optimized for harmonics generation and may differ from specified in the table.
  2. Unless stated otherwise all specifications are measured at 2500 Hz pulse repetition rate.
  3. Unless stated otherwise all specifications are measured at 1000 Hz pulse repetition rate.
  4. 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.
  5. Averaged from pulses emitted during 30 sec time interval.
  6. FWHM at 1064 nm.
  7. Measured over 8 hours period after 20 min warm-up when ambient temperature variation is less than ± 2 °C and humidity <± 5%.
  8. Full angle measured at the 1/e² level at 1064 nm.
  9. Beam diameter is measured at 1064 nm at the 1/e² level.
  10. Beam pointing stability is evaluated as movement of the beam centroid in the focal plane of a focusing element.
  11. With respect to QSW IN or SYNC OUT pulse.
  12. 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.
