NL210 Series - Diode-pumped, Actively Q-switched Nd:YAG Lasers

The diode-pumped, actively Q-switched nanosecond laser NL210 delivers up to 10 mJ at 3 - 4 ns at a 1 kHz repetition rate. Optionally, temperature stabilized second, third and fourth harmonic generators are available. The built-in water-to-air chiller eliminates the need for external cooling. Short pulse duration, high energy and close to TEM00 beam profile make this laser suitable for many different applications.

NL210 series diode pumped Q-switched lasers produce up to 10 mJ at 1000 Hz pulse repetition rate. The laser is designed to produce high intensity, high brightness pulses and is targeted for applications like OPO pumping, nonlinear spectroscopy, material ablation, micromachining, and other tasks.

Employing electro-optical type of the cavity dumping, the master oscillator can produce pulses with a short pulse duration of 3 – 4 ns, the uniform beam profile and low divergence. The M² factor of the beam is typically between 3 – 4. Laser cooling uses a closed loop chiller, thus eliminating the need for external cooling water, and reducing running costs.

Angle-tuned LBO and/or BBO crystals mounted in temperature stabilized heaters are used for optional second, third or fourth harmonic generation. The harmonic separation system is designed to ensure a high spectral purity of radiation directed to separate output ports.

For customer convenience the laser can be controlled from a remote control pad or USB interface. The remote pad allows easy control of all parameters and features a backlit display that is easy to read even wearing laser safety eyewear. Alternatively, the laser can be controlled from a personal computer with supplied software for a Windows™ operating system. LabVIEW™ drivers are supplied as well.
