Collimated output mid infrared quantum cascade laser DFB-CW QCL
Collimated output mid infrared quantum cascade laser DFB-CW QCL
Product details
Distributed feedback continuous collimated output quantum cascade laserDFB-CW QCL，Mid infrared, light output20mW
Hamamatus PhotonicsDistributed feedback continuous collimated output quantum cascade laserDFB-CW QCLIt has been validated by the market. There are wavelengths available4.57、5.26、4.57、4.33、5.26、6.13um, Power20mWOptional disc-shaped packaging. Wavelength tuning range with forward voltage>0.4 cm-1Beam divergence angle0~5 mrad(Typical)3mrad）. Small in size and lightweight, suitable for industrial integration.
The typical system structure is as follows: the laser chip is connected to a copper carrier throughHHLIn the form of packaging, the output is collimated through a collimating lens.TEC（Thermo Electric Cooler）Also known as a semiconductor cooler, it is made using the Peltier effect of semiconductor materials. When a direct current passes through a thermocouple composed of two semiconductor materials, one end absorbs heat and the other end releases heat.
The Hamamatsu mid infrared broadband quantum cascade laser in Japan is a distributed feedback quantum cascade laser, comes with optional accessories:TECTemperature controllerHHLCheckpoint, cable, lens/Camera unit, etc.
