NL310 series high energy nanosecond q-switched Nd:YAG lasers


High pulse energy nanosecond Q-switched lasers of NL310 series are targeted for applications like OPO or Ti:S pumping, material processing and plasma diagnostics. The lasers can produce pulse energies up to 5 J at 1064 nmat 10 Hz pulse repetition rate. Customized versions of lasers are available producing pulse energies up to 10 J at 1064 nm or repetition rates up to 30 Hz.

For the convenience of customers, the NL310 series nanosecond Q-switched laser can be controlled either through a user-friendly remote keypad or RS232/USB port. The remote keypad allows easy control of all the parameters and features a backlit display that is easy to read even while wearing laser safety eyewear.

For control from personal computer software for Windows™ operating system is provided. LabView™ drivers are supplied as well, allowing laser control integration into existing Labview™ programs.

The optional second (SH, 532 nm), third (TH, 355 nm), fourth (FH, 266 nm) and fifth (FiH, 213 nm) harmonic generators can be integrated into laser head or placed outside laser head into auxiliary harmonics generator module. Output wavelength switching is done manually, motorized wavelength switching is available by request. Triggering of the laser is possible from build-in internal or from external pulse generator. Pulses with TTL levels are required for external triggering. In both cases laser pulses have less than 0.5 ns rms jitter in respect to Q-switch triggering pulse.

The simple and field proven design ensures reliable long-term operation of laser and easy maintenance.
