Abstract: PROBLEM TO BE SOLVED: To provide a microcylinder type solid-state laser having by for an elevated output power and directivity of the output beam. SOLUTION: A solid-state laser 10 comprises a cylindrical resonator 12 having a curved boundary, and solid-state active region 12.1 located in the resonator, which is capable of generating a laser beam when it is pumped appropriately. The resonator has a comparatively high effective refractive index n (n>2, generally n>3) and a deformed shape sufficient for supporting at least a liberation mode (e.g. a V-mode or bow-tie type mode; the latter is preferable for generating a directive output of a comparatively high power), and for a specific example of a III-V compound semiconductor quantum cascade microcylindrical laser device, the resonator has a shape deformed according to a flat quadrupole deformation function from a circular shape.

Abstract: A solid state laser comprises a cavity resonator in the form of a generally cylindrical body and, located within the resonator, an active region which generates lasing light when suitably pumped. The resonator has a relatively high effective refractive index (n > 2 and typically n > 3) is sufficiently deformed from circularity so as to support at least one librational mode (e.g., a V-shaped or a bow-tie mode, the latter being presently preferred for generating relatively high power, directional outputs). Specifically described is a Group III-V compound semiconductor, quantum cascade (QC), micro-cylinder laser in which the resonator has a flattened quadrupolar deformation from circularity. This laser exhibits both a highly directional output emission and a three-order of magnitude increase in optical output power compared to conventional semiconductor micro-cylinder QC lasers having circularly symmetric resonators.
