Germanium Window for Infrared Laser / OPGE
Silicon is a mono crystal primarily used in semi-conductor and is non-absorptive at 1.2μm to 6μm IR regions. It is used here as an optical component for IR region applications.
◦These silicon windows do not transmit at 1µm region or below, therefore its main application is in IR regions.◦Because of its high thermal conductivity, it is suitable for use as a high power laser mirror
