Diode pumped nanosecond lasers NL220 series provide up to 10 mJ per pulse at 1 kHz repetition rate. Featuring compact size and turnkey operation, NL220 series diode pumped nanosecond lasers are ideal for integration into other systems. In addition, a very low jitter of optical pulse with respect to sync pulse allows reliable synchronization with external equipment.
Short pulse duration, TEM₀₀ beam, high energy and variable repetition rate establish the NL220 series diode pumped nanosecond lasers as an excellent choice for many applications, including micromachining, material processing, marking, laser spectroscopies and other R&D as well as industrial tasks. PIV version of this laser is available.
For customer convenience, the laser is controlled through RS232 or USB type PC interface with LabView drivers (included) or a user-friendly remote control keypad. Either option allows easy control of laser settings. Closed loop chiller eliminates the need for external cooling water.
