1W 785nm Laser Chip On Submount

Like the C-mount, the CoS (chip on submount) has the laser exposed without protection to the chip or its bond wires. User should be knowledgeable in the handling and mounting of this type package. The CoS is also highly desired when other optical components need to be in very close proximity to the front facet. The AlN submout is an excellent conductor of heat but the CoS will require cooling.
