Q-SPARK is diode pumped, water-free, Q-switched laser designed for wide range of applications that require high peak power short pulses.
Our innovative water-free laser crystal end-pumping technology allows to produce Gaussian-like, low divergence, high peak power laser beam in compact package.
Due to short laser cavity laser delivers up to 5 mJ at < 800 ps pulse duration or up to 10 mJ at < 1.5 ns pulse duration. Models with pulse repetition rates up to 100 Hz are available.
Cost-effective version of the laser with passive Q-switch is available. It should be noted, that for passive Q-switched laser, the laser pulse jitter is larger in comparison to actively Q-Switched lasers (see datasheet for details).
For active Q-Switch type, 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 precisely triggered from auxiliary delay generator.
Laser is monitored and 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 Q-SPARK. API is also provided for integration with user devices.

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

Up to fourth harmonic output wavelength can be produced build-in harmonics generator, located inside laser body. See datasheet below for pulse energy specifications.
Pulse energy can be adjusted with our attachable motorized attenuator for fundamental or harmonic wavelength beam.
Pulse energy can be monitored by our attachable pulse energy monitor with analog and/or digital output.
Residual harmonic generator wavelengths can be accessed with optional auxiliary exit port.
Fiber coupled output is available by request. Please inquire for detailed specifications.

  1. 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.
  2. Factory-set pulse repetition rate is fixed at max repetition rate shown in the table.
  3. At FWHM level at fundamental wavelength, measured with 350 ps rise time photodiode. Short pulse duration version is available, with pulse duration shorter by approx 50%. Inquire for detailed specifications.
  4. Measured during 30 seconds operation after warm-up.
  5. SLM pulses are produced for >95% of operating time.
  6. Over 8 hour period after 20 minutes of warm-up when ambient temperature variation is less than ±2 °C.
