Abstract

The invention provides a single-chip microchip laser, and the laser comprises a pumping source for emitting pumping light with the wavelength of 808nm; a gain medium which at least comprises a top surface, a first side surface and a second side surface, wherein the first side surface and the second side surface are respectively connected with the top surface and respectively form acute angles withthe top surface. a double-color film which is arranged on the top surface and is close to the pumping source, and a 1064nm partial reflection film which is arranged on one side, far away from the pumping source, of the top surface; a first Q-switched crystal and a second Q-switched crystal which are respectively arranged on the first side surface and the second side surface, and are used for generating Q-switched pulses. In this way, the average power and the light beam quality of lasers emitted by the single-chip microchip laser can be improved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a single-chip microchip laser. Background technique [0002] Monolithic microchip lasers generally include resonators, Q-switched devices, and laser gain crystals. They have the advantages of small size, high beam quality, and narrow pulse width. They are mainly used in laser imaging, industrial processing, biomedicine, and military applications. Probe field. [0003] The current microchip laser requires excellent output laser power while requiring small size. For the output pulse, the laser of a certain wavelength is generally oscillated through the resonator to form a pulse laser of another wavelength. The shape of the laser resonator is single, which is formed between the Q-switched crystal and the gain medium, and the laser propagation distance in the resonator is too short and limited by the shape of the crystal, so the power and quality of the output laser are average, and ...
