High-energy nanosecond pulses, excellent beam quality and 1% pulse energy stability make these nanosecond Q-switched Nd:YAG lasers an excellent choice for pumping of dye, Ti:Sapphire lasers and OPOs. In addition, the extremely low jitter of the optical pulse with respect to the sync pulse allows for the reliable synchronisation of the laser with external equipment.
For the convenience of customers, the NL310 series nanosecond Q-switched laser is controlled either through its RS232 type PC interface with LabView™ drivers (included), or through a user‑friendly remote control pad. Both options allow for the easy control of laser settings. The compact size enables the system to fit into tight spaces, freeing the experiment area for other instruments. The power supply and cooling unit fit easily under optical tables. The optional second (SH) (for 532 nm), third (TH) (for 355 nm) and fourth (FH) (for 266 nm) harmonic generator modules are designed for easy insertion and removal.
The simple and proven design ensures the easy maintenance and long-term stability of laser operation.
