NL310 Series - Flashlamp-pumped High Energy Nanosecond Lasers

The high energy lasers of the NL310 series deliver up to 10 J at up to 20 Hz repetition rate and pulse durations of 4 - 7 ns. The excellent beam quality and 0.5% pulse energy stability make this nanosecond laser an excellent choice for pumping dye, Ti:Sapphire lasers and OPOs. In addition, extremely low jitter of optical pulse with respect to sync pulse allows a reliable synchronisation with external equipment.

Description 

Features

  • Up to 10 J output energy
  • Better than 0.5% rms pulse energy stability
  • 4 – 6 ns pulse duration
  • 10 or 20 Hz repetition rate
  • Temperature  stabilized second, third, fourth and fifth harmonic generators
  • Remote control via keypad  or USB-CAN port
  • Low jitter internal/external synchronization
  • Robust and stable laser head

Applications

  • OPO, Ti: Sapphire, dye laser pumping
  • Material processing
  • Plasma generation and diagnostics
  • Nonlinear spectroscopy
  • Remote sensing

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 user-friendly 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 harmonics 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 harmonics generator option.

3) For -SH/TH harmonics generator option.

4) For -SH/FH, -SH/TH/FH or -SH/FH/FiH harmonics generator option.

5) For -SH/FH/FiH harmonics generator option.

6) Harmonics outputs are not simultaneous; only single wavelength beam is present at the output at once. Manual reconfiguration is required to switch wavelength.

7) FWHM.

8) Near field (at the output aperture) TOP HAT fit is >70%.

9) Averaged from pulses, emitted during 30 sec time interval after 5 – 15 minutes of 
warm-up.

Options 

Option G: For models NL311, NL313. Provides beam profile optimized for OPO pumping or other applications requiring smooth, without hot spots beam profile in the near and medium field. Pulse energies typically are lower by 30% in comparison to standard lasers without -G option.

Multimode spatial beam profile for smooth envelope. M² > 20.

RLI. Optional Relay Imaging for smooth beam profile.
