NL230 Series - Diode-pumped, Actively Q-switched Nd:YAG Lasers

The diode-pumped nanosecond Q-switched lasers of the NL230 series produce up to 150 mJ at 100 Hz or up to 190 mJ at 50 Hz pulse repetition rate. Diode pumping allows maintenance-free laser operation for an extended period of time (more than 3 years for an estimated eight working hours per day). The typical pump diode lifetime is more than 1 billion shots.

Description 

Features

  • Diode-pumped
  • Rugged sealed laser cavity
  • Up to 190 mJ at 1064 nm pulse energy
  • Up to 100 Hz pulse repetition rate
  • Short pulse duration in the 3 – 6 ns range
  • Variable reflectivity output coupler for low-divergence beam
  • Quiet operation: no more flashlamp firing sound
  • Remote control via keypad and/or any controller running on any OS using REST API commands
  • Optional temperature-stabilized second and third harmonic generators
  • Electromechanical shutter (optional)
  • Easy replaceable output window

Applications

  • LIBS (Light Induced Breakdown Spectroscopy)
  • Material ablation
  • OPO pumping
  • Remote Sensing
  • LIDAR (Light Detection And Ranging)
  • Mass Spectroscopy
  • LIF (Light Induced Fluorescence)

Benefits

  • Short duration 3 – 6 ns pulses ensures strong interaction with material, are highly suitable for LIBS
  • User selectable wavelength single axis output is superior for experiments, where alternating wavelengths are required, like material ablation, LIBS
  • Rugged, monolithic design enables laser usage in hash environment
  • Diode pumped design provides quiet operation, eliminates the irritation of flash light
  • Variety of interfaces USB, RS232, LAN, WLAN ensures easy control and integration with other equipment

 

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. Diode pumping allows maintenance-free laser operation for an extended period of time – more than 3 years for an estimated eight working hours per day.

Because laser head components are placed in a robust, sealed and precisely machined monolithic aluminium block, this laser can reliably work in a harsh industrial environment with applications such as laser-induced breakdown spectroscopy (LIBS).

Second and third harmonic options allows for an expanded range of applications, where high pulse energy and high pulse to pulse stability are required.

For easy and seamless control and integration with other industrial equipment, the NL230 series laser is equipped with USB/RS232 interfaces and can be externally triggered with a jitter as low as < 0.5 ns rms.

NL230 series lasers are designed to work reliably 24/7 in an industrial environment.
