LASER DIODE SIDE PUMPING OF AN ELONGATED SOLID-STATE LASER WITHOUT FOCUSING/OPTICS

摘要

The side pumping lasers include an elongated gain medium 10 supplied between the output coupler 20 and the counter reflector 15 and a pump source 65 configured to supply radiation to the gain medium along the side or long axis of the gain medium 10. [ ), A laser formed such that radiation from the pump source is projected directly onto the gain medium; And a pump source that is contiguous and supplied in contact with the gain medium in close proximity or in contact. The laser materials and components, geometries and dimensions maximize the performance of the laser and enable the use of common construction techniques in the production of equipment designed for optical telecoms systems, It is designed to enable. While other non-emitting surfaces are coated with a golden coating for pump light recycling and cooling of the gain medium, for example by thermal conductivity, the elongated gain medium The laser diode 10 may have a cross-section with an uncoated side surface 55 that receives pump light emitted by a laser diode bar 65. The counter reflector 15 may be provided on one side of the passive cue switch 30 and the output coupler 20 may be provided on one side 50b of the gain medium 10.
