NL300 series electro-optically Q-switched nanosecond Nd:YAG lasers produce high energy pulses with 3 – 6 ns duration. Pulse repetition rate can be selected in range of 10 – 30 Hz.
NL30×G models are optimized for OPO pumping that requires smooth beam profile without hot spots.
NL30×HT models are designed for maximum energy extraction from the active element. Up to 800 mJ pulse energy can be produced at a 10 Hz pulse repetition rate.
A wide range of harmonic generator modules for generation up to a 5th harmonic is available.
Harmonics generators can be combined with attenuators that allow smooth output energy adjustment without changing other laser parameters, i.e. pulse duration, pulse-to-pulse stability, divergence or beam profile. For a more detailed description of harmonic and attenuator modules please check our harmonic generators selection guide.
The extremely compact laser head is approximay 480 mm long and can be fitted into tight spaces. The laser power supply has a 330 × 490 mm footprint. Easy access to the water tank from the back side of the power supply facilitates laser maintenance. Replacement of flashlamp does not require removal of pump chamber from the laser cavity and does not lead to possible misalignment. The powering unit can be configured with water-to-water or water-to-air heat exchangers. The latter option allows for laser operation without the use of tap water for cooling.
For customer convenience the laser can be controlled via a RS232 or USB port with LabView™ drivers (included) or a user-friendly remote control pad. Both options allow easy control of laser settings.
