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.

Description 

Features

  • Up to 4 mJ pulse energy at 1064 nm
  • Up to 2500 Hz variable repetition rate
  • 532 nm, 355 nm, 266 nm, 213 nm wavelengths as standard options
  • <10 ns pulse duration at 1064 nm
  • Electro-optical Q-switching
  • Turn-key operation
  • Rugged sealed cavity
  • Extremely compact size
  • Simple and robust
  • Air cooled
  • External TTL triggering
  • Remote control via keypad and/or any controller running on any OS using REST API commands

Applications

  • Material processing
  • LCD and OLED display panel repair
  • Marking
  • Micromachining
  • Engraving
  • Laser deposition
  • Laser cleaning
  • Ablation
  • Spectroscopy
  • OPO pumping
  • Remote sensing

Benefits

  • Continuous tuning of repetition rate while maintaining constant pulse energy, superior beam pointing and energy stability make the laser the first choice for micromachining, marking, thin film removing applications
  • Close to Gaussian smooth beam profile with low value M² < 1.3 and good focusability is beneficial for such applications, as LCD and OLED display repair
  • Compactness and lightness make a laser easy transportable, saves on valuable laboratory space
  • Fast wavelength selection is superior for applications where alternating wavelengths are required, like material ablation, LIBS
  • Air cooling, cheap and reliable end-pumping technology, amplifiers free DPSS design guarantee easy operation and alignment of laser, simple installation and low life-time ownership cost
  • Variety of control interfaces USB, RS232, LAN, WLAN ensure easy control and integration of laser with laboratory or OEM equipment

 

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.
