The NL230 series of diode-pumped Q-switched lasers produce up to 150 mJ at 100 Hz or up to 190 mJ at 50 Hz pulse repetition rate. Due to an electro-optical Q-switch, the master oscillator generates short duration pulses in the 5 - 9 ns range. It has 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. The pump diode lifetime is more than 1 billion shots. These lasers are ideal for applications such as material ablation, remote sensing, OPO, Ti:Sapphire or dye laser pumping.
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.
