High Energy Q-switched Nd:YAG Lasers
High pulse energy NL310 series lasers are targeted for applications like OPO or Ti: Sapphire pumping, material processing and plasma diagnostics. These lasers can produce pulse energies up to 10 J in fundamental wavelength at 10 Hz pulse repetition rate.
For the convenience of customers the NL310 series nanosecond Q-switched laser can be controlled either through a remote keypad or USB-CAN port. The remote keypad allows easy control of all parameters and features a backlit display that is easy to read even wearing laser safety eyewear.
Software for Windows™ operating system is provided to control the laser from PC. 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 20harmonic generator module. Output wavelength switching is done manually. Motorized wavelength switching is available by request.
Triggering of the laser is possible from built-in internal or external pulse generator. Pulses with TTL levels are required for external triggering. Laser pulses have less than 0.5 ns rms jitter with respect to Q-switch triggering pulse in both cases.
The simple and field proven design ensures easy maintenance and reliable long-term operation of the NL310 series laser.

1) Due to continuous improvement, all specifications subject to change without notice. Parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 1064 nm and for basic system without options.
2) For -SH harmonic generator option.
3) For -SH/TH harmonic generator option.
4) For -SH/FH, -SH/TH/FH or -SH/FH/FiH harmonic generator option.
5) For -SH/FH/FiH harmonic generator option.
6) Harmonic outputs are not simultaneous; only single wavelength beam is present at the output at once. Manual reconfiguration is required to switch wavelength.
7) Averaged from pulses, emitted during 30 sec time interval after 5 – 15 minutes of warm-up.
8) Measured over 8 hours period after 20 min warm-up when ambient temperature variation is less than ±2 °C.
9) FWHM.
10) Standard deviation value, measured with respect to Q-switch triggering pulse.
11) Near field (at the output aperture) TOP HAT fit is >70%.
12) Beam diameter is measured at 1064 nm at the 1/e² level.
13) Full angle measured at the 1/e² level at 1064 nm.
14) Beam pointing stability is evaluated as movement of the beam centroid in the focal plane of a focusing element.
15) Water air cooling chiller is possible. Inquire for details.
16) Mains voltage should be specified when ordering

ORDERING INFORMATION
Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
