Q1 is compact, energy-efficient, diode pumped, air-cooled, Q-switched laser designed for wide range of applications that require high peak power pulses.
Laser can produce up to 45 mJ at 10 Hz pulse repetition rate or up to 10 mJ at 50 Hz pulse repetition rate.
Low divergence of laser beam allows efficient conversion to harmonic wavelengths using optional H1 series harmonic generator module.
The laser 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 significant changes in beam divergence or profile.
Innovative laser design resulted in 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 Q1 housing and the only external modules are lightweight controller box that provides laser control interfaces and mains adapter that provides 12 VDC powering. Total weight of the laser is less than 5 kg.
Laser is monitored and controlled trough Ethernet port via build-in web-server. Any computer or even cell phone with modern web-browser will be able to control Q1. API is 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.
Laser functionality can be further extended by wide selection of auxiliary equipment:
Up to fifth harmonic output can be produced from our stand-alone H1 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.
Fiber coupled output is available by request. Please inquire for detailed specifications.

- Due to continuous improvements all specifications are subject to change. Unless stated otherwise all specifications are measured at fundamental wavelength and maximum pulse repetition rate. The parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture.
- Factory-set pulse repetition rate is fixed at max repetition rate shown in the table. Smoothly variable pulse repetition rate is possible when laser is externally triggered. In internal triggering mode repetition rate can be divided by integer number down to f/2, f/3, f/4,.. 1 Hz.
- At FWHM level at fundamental wavelength, measured with 350 ps rise time photodiode.
- Pulse energies for harmonic wavelengths are maximum possible values available from H1 series harmonic generator module. See datasheets of H1 for details.
- Measured during 30 seconds operation after warm-up.
- Over 8 hour period after 20 minutes of warm-up when ambient temperature variation is less than ±2 °C.
- Full angle measured at the 4σ level.
- Peak to peak value, measured for 30 seconds of operation after laser warm-up.
- Beam diameter is measured 20 cm from laser output at the 4σ level.
- In respect to falling edge of pump diode triggering pulse.
- Motorized attenuator intended to be attached to the laser housing. Transmission can be changed remotely trough laser web-server control interface.
- Power adapter dimensions might differ from indicated here, depending on model.
- Q1 laser is compatible all models of stand-alone H1 harmonics generator. Please refer to harmonic generator datasheets for detailed specifications.
- Laser can be powered from appropriate 12 VDC power source. Please inquire for details.
