Novel microchip laser supporting optical fiber output

Abstract

The invention discloses a novel microchip laser supporting optical fiber output, which belongs to the fields of laser technology and non-linear optics. The novel microchip laser mainly comprises a laser diode pumping source, an optical fiber output system, an optical collimation system, a laser light gain medium and optical elements, wherein pump light enters the optical collimation system for collimating after passing through the optical fiber output system, and is focused onto the gain medium; the film-plated optical elements are arranged in front of and behind the gain medium; the gain medium and the film-plated optical elements in front of and behind the gain medium construct a laser resonant cavity with a sandwich structure; laser light generated by the laser resonant cavity returns along the incident direction of the pump light, passes through the optical collimation system once again, and is output through the optical fiber output system. The novel microchip laser has the characteristics that optical fiber output is performed during the use of an optical fiber pump without any additional output device in a sandwich microchip structure, and a fiber-core pump or a cladding pump can be adopted, so that the flexibility of a system is improved greatly; and meanwhile, the structure can also be applied to pulse modulation of materials such as semiconductor saturable absorbing mirrors, single-wall carbon nanotubes or graphene and the like, and stable pulse output is realized.
