Q2 series diode pumped, fully air-cooled, Q-switched laser is designed for wide range of applications that require high peak power pulses.
Our innovative water-free laser crystal end-pumping technology allows to produce Gaussian-like, low divergence laser beam. At the same time, Q2 is versatile platform that can be configured in many ways.
For example, Q2 be configured for 80 mJ pulse energy at 10 Hz pulse repetition rate. For high repetition rate configuration laser can produce up to 20 mJ at 100 Hz.
Q2 can configured to emit 1053 nm or 1064 nm wavelength from Nd:YLF or Nd:YAG laser crystals respectively. Due athermal properties of Nd:YLF crystal, at 1053 nm the laser can operate from single shot to maximum pulse repetition rate without changes in beam divergence or profile.
In short cavity configuration pulse duration can be reduced by 50% in comparison to standard configuration. Peak power of pulse can reach more than 30 MW at pulse energy up to 60 mJ.
Thermo-electric cooler based temperature control system eliminate risks associated with water cooling (leaks, organic contamination etc.) and reduce maintenance costs. If requested, standard fan-cooled heatsink can be detached from the laser body and laser can be mounted on user-supplied cold plate or other cooling system.
Innovative laser design resulted in compact, user-friendly turnkey system that requires little maintenance. There is no chillers or bulky power supplies that one needs fit under the table. All laser electronics is integrated into Q2 housing and the only external modules are lightweight controller box that provides laser control interfaces and mains adapter that provides 12 or 28 VDC, 30-100 W powering (depending on model).
Laser is controlled trough Ethernet port via build-in web-server. There is no need to install control software – any computer or even cell phone with modern web-browser will be able to control Q2. API is also provided for integration with user devices.
Low jitter triggering pulses for user equipment are available with up to 300 µs lead in internal triggering mode. In external triggering mode, laser pulsing can be externally triggered from delay generator.
The laser specifications for different pulse repetition rates are summarized in the tables below.

Laser functionality can be further extended by wide range of auxiliary equipment:

  • Second harmonic output can be produced from our attachable 2nd harmonic generator, model SHG.
  • Up to fifth harmonic output can be produced from our stand-alone H-SMART series harmonic generators.
  • Pulse energy can be adjusted with our motorized attenuator for fundamental wavelength beam.
  • Pulse energy can be monitored by our attachable pulse energy monitor with analog and/or digital output.
