NL300 series electro-optically Q-switched nanosecond Nd:YAG lasers provide up to 800 mJ per pulse with excellent stability. They can be operated from a standard outlet and with water-air heat exchanger eliminating the need for external cooling water. The NL300 series lasers are an excellent choice for many applications, including laser ablation and marking, OPO pumping and other critical tasks. A compact laser head measures only 48 cm (less than 20 inches) and fits nicely into tight spaces. Optional second (SH, 532 nm), third (TH, 355 nm) and fourth (FH, 266 nm) harmonic generator modules are designed for easy attachment and removal. Power supply and cooling units are also compact and easily accommodated under tables.
For customer convenience, the laser is controlled either through its RS232 type PC interface with LabView drivers (included) or a user-friendly remote control keypad. Both options ensure easy control of laser settings. In addition, a very low jitter of optical pulse with respect to sync pulse allows reliable synchronization with external equipment.
The NL300G series lasers are best suited for OPO pumping and other critical set-ups.
The NL300HT series lasers are preferable for most applications, including laser ablation and marking.
