Multilevel laser medium has layer that is made of laser material, which is excited to stimulate emission on laser wavelength, and has another layer that is made of absorber material that works to absorb same wavelength

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a multi-level laser medium consisting of a laser material layer, which emits light when excited, and an absorber material layer, which absorbs light at the same wavelength as the emitted laser. These layers are optically connected either directly or through an intermediate layer. The structure features a specific geometric form for efficient functioning, and can use specialized crystals like gadolinium scandium aluminum garnet.

Patent Abstract

The multilevel laser medium has a layer (3) that is made of a laser material, which is excited to stimulate emission on a laser wavelength, and has another layer (1) that is made of an absorber material that works to absorb the same wavelength. The two layers are optically coupled together directly or over an intermediate layer (2). The entire layer structure has five-angular form, and extends perpendicularly to the cross section over a desired length. An independent claim is included for gadolinium scandium aluminum garnet crystal.
