The NL230 series diode-pumped nanosecond Q-switched lasers produce up to 50 mJ at 100 Hz or up to 150 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.

The NL230 series diode-pumped Q-switched nanosecond lasers produce up to 100 mJ at 100 Hz or up to 150 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.
Lasers are designed to produce high-intensity, high-brightness pulses and are targeted for applications such as material ablation, remote sensing, OPO, Ti:Sapphire or dye laser pumping. Due to an electro‑optical Q-switch, the master oscillator generates short duration pulses in the 5 – 9 ns range. The oscillator cavity optical design features a variable‑reflectivity output coupler, giving a low-divergence laser beam.
A closed-loop TEC based chiller is used for laser cooling, eliminating the need for external cooling water and reducing running costs. Angle-tuned non-linear crystals mounted in temperature stabilized heaters are used for optional second, third or fourth harmonic generation. The harmonics separation system is designed to ensure radiation with a high spectral purity and to direct it to the separate output ports.
For customer convenience the laser can be controlled via a user‑friendly remote control pad or a USB interface. The remote pad allows easy control of all parameters and features a backlit display that is easy to read even through laser safety eyewear. Alternatively, the laser can be controlled from a personal computer via supplied Windows™ compatible software. LabVIEW™ drivers are also included with each laser installation package.
