About microchip


The Microchip (MC) consists of a saturable absorber bonded with a Nd:YVO4 laser crystal. It can be used to generate pulsed laser radiation at 1064 nm wavelength if pumped with a diode laser at 808 nm using passively Q-switching.
The main advantage of a laser build with a microchip is the pump power dependent repetition rate with fixed pulse duration and pulse energy. By simply increasing the pump power at 808 nm the repetition rate - and consequently the average output power - will be increased proportionally starting from the laser threshold.
The laser output is linear polarized.

We provide two types of microchips

  • MC - Microchip in reflection mode
  • MCT - Microchip in transmission mode.

Possible application areas of this laser radiation are:

  • micromachining
  • light detection and ranging (LIDAR)
  • precision measurements
  • frequency conversion
MC - Microchip in reflection mode
  • The Nd:YVO4 laser crystal is bonded with a saturable absorber mirror (SAM).
  • The laser output beam is in the reverse direction of the pump beam and must be separated from pump light by using a dichroitic mirror.
  • The laser output is linear polarized with the polarization direction perpendicular to the groove in the copper heat sink.
