Strip-loading device used for cavity surface coating of semiconductor laser

Abstract

The invention discloses a strip-loading device used for cavity surface coating of a semiconductor laser. The strip-loading device used for cavity surface coating of the semiconductor laser comprises abase, wherein an inner cavity mechanism is arranged on the lower surface of the base, and a clamping mechanism is installed in the inner cavity mechanism. When the strip-loading device used for cavity surface coating of the semiconductor laser is used, a first rotating rod is rotated through a rotating handle, the first rotating rod drives two first bevel gears, to rotate in an opposite direction, through two second bevel gears, meanwhile, the two first bevel gears drive two driving gears, to rotate synchronously, through third rotating rods, the two driving gears drive two clamping rods, torotate, through cooperation of the two driving gears and driven gears, thus a cleavage strip can be clamped and fixed through synchronous rotation of the two clamping rods, meanwhile, a sliding blockand a sliding rod can be limited by a sliding cavity and a sliding hole, and thus rotating angles of the rotating handle and the clamping rods are limited, so that not only is loading work simple andconvenient, but also damage, due to excessively-tight clamping, to the cleavage strip can be avoided.

Description

technical field [0001] The invention belongs to the technical field of laser cavity surface coating, in particular to a strip loading device for semiconductor laser cavity surface coating. Background technique [0002] Since the advent of semiconductor lasers in the early 1960s, it has attracted more and more attention due to its many advantages, but the natural cleavage cavity surface of semiconductor lasers has a reflectance of about 30%, which is not an ideal value. , and this natural cleavage surface is easily oxidized or polluted in the air, which reduces the performance of the laser. In order to solve these problems, the cavity surface is usually coated in the semiconductor laser manufacturing process, and the light-emitting surface is coated with A transparent film is used to increase its transmittance, and a high reflective film is coated on the other side to increase its reflectance, which also protects the cavity surface, and the existing cavity surface coating pro...
