Abstract
Abstract A high power, compact waveguide gas laser having a housing located within a resonant cavity. The housing has a longitudinal chamber situated therein, the chamber being divided into a plurality of waveguides by a plurality of infrared transmitting partitions. During operation of the laser, the leakage of laser radiation between adjacent waveguides through the partitions causes the coupling of the phases of the waveguide modes thereby producing a laser output of high power.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A high power compact waveguide laser comprising a resonant cavity, an elongated housing located within said resonant cavity, a longitudinal chamber located within said housing and containing a lasing medium, means for dividing said longitudinal chamber into a plurality of longitudinal waveguides, said dividing means being transmissive to the emission wavelength of said lasing medium, means for admitting said lasing medium into said waveguides and means for causing a lasing action to take place within said lasing medium located within each of said waveguides whereby leakage of laser radiation between adjacent waveguides through said dividing means causes the coupling of the phases of the waveguide modes and thereby produces a laser output of high power.
Claim 2
Dependent Claim
115 words
A high power compact waveguide laser comprising a resonant cavity, an elongated housing located within said resonant cavity, a longitudinal chamber located within said housing and containing a lasing medium, means for dividing said longitudinal chamber into a plurality of longitudinal waveguides, said dividing means being transmissive to the emission wavelength of said lasing medium, means for admitting said lasing medium into said waveguides and means for causing a lasing action to take place within said lasing medium located within each of said waveguides whereby leakage of laser radiation between adjacent waveguides through said dividing means causes the coupling of the phases of the waveguide modes and thereby produces a laser output of high power.
