產(chǎn)品介紹
MC – 反射模式微芯片(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.

Microchip description and applications
The Microchip (MC) consists of a saturable absorber mirror bonded with a Nd:YVO4 laser crystal. The MC can be used to generate pulsed laser radiation at 1064 nm wavelength if pumped with a pump diode at 808 nm. Possible application areas of this laser radiation are:
- l ?micromachining
- l ?light detection and ranging (LIDAR)
- l ?precision measurements
- l ?frequency conversion
The main advantage of a laser build with this 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.
