MCT – 传输模式微芯片(Microchip in transmission mode)

The Nd:YVO₄ laser crystal is bonded with a saturable output coupler (SOC).
The laser output beam is in the same direction as the pump beam.
The laser output is linear polarized.

Part No.		Delivery time	Description
MCT-1064-90ps	1 week		Microchip in transmission mode λ = 1064 nm, pulse duration ~ 90 ps, pulse energy ~ 100 nJ, repetition rate 20 kHz - 400 kHz pump wavelength 808 nm
MCT-1064-220ps	1 week		Microchip in transmission mode λ = 1064 nm, pulse duration ~ 220 ps, pulse energy ~ 160 nJ, repetition rate 20 kHz - 400 kHz pump wavelength 808 nm

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:

micromachining
light detection and ranging (LIDAR)
precision measurements
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.
