Abstract
Abstract A slab waveguide pumped channel waveguide laser includes a slab waveguide having a primary pump guiding layer with a first index of refraction and having first and second opposing faces and a peripheral edge including a mirrored surface, and cladding means having a second index of refraction lower than the first index of refraction, proximate the first and second opposing faces; at least one rare earth doped channel waveguide laser having a third index of refraction higher than the first index of refraction disposed in the primary guiding layer; and means for introducing pumping energy into the guiding layer to reflect between the mirror surfaces and energize the laser.
