Laser device with a convergent reflector topology

摘要

A laser device, having an optical cavity containing a gain medium, a total reflectance reflector positioned within the optical cavity, and a partial reflectance reflector positioned within the optical cavity in a juxtaposed relationship to the total reflectance reflector. The topology of the reflectors are defined by a convergent reflector topology function that converges light emitted within the optical cavity to a laser beam that exits the optical cavity through the partial reflectance reflector by a series of reflections between the total reflectance reflector and the partial reflectance reflector. The laser beam emitted from the optical cavity has a predefined pattern for a given convergent reflector topology.

1. A laser device, having an optical cavity containing a gain medium, a total reflectance reflector positioned within the optical cavity, and a partial reflectance reflector positioned within the optical cavity in a juxtaposed relationship to the total reflectance reflector, comprising:
wherein the total reflectance reflector has a first surface topology; wherein the partial reflectance reflector has a second surface topology; wherein at least one of the first surface topology and the second surface topology is defined by a convergent reflector topology function that converges light emitted within the optical cavity to a laser beam that exits the optical cavity through the partial reflectance reflector by a series of reflections between the total reflectance reflector as defined by the first surface topology and the partial reflectance reflector as defined by the second surface topology; and wherein the laser beam emitted from the optical cavity has a predefined pattern for a given first surface topology and a second surface topology.
