Problems solved by technology

[0006] 2. Small processing errors between the three reflective surfaces of the corner cube will lead to a very large loss of laser power
However, the above two solutions still require the retro-reflector to be aligned on the central axis of the system, and can only achieve angular adjustability around the central axis

Abstract

The present invention provides a laser oscillator based on a telepentric cat eye structure. The laser oscillator adopts an all-trans telecentric cat eye, a gain medium and at least one output telecentric cat eye. The system constitutes an all-trans telecentric cat eye by using a total reflection mirror and a first lens, and each output telecentric cat eye is composed of a second lens and an outputcoupling mirror. The gain medium is placed at the focal point of the all-trans telecentric cat eye. The focal point of each output telecentric cat eye is located in the field of view of the all-transtelecentric cat eye, and the focal point of the all-trans telecentric cat eye is located in the view of each output telecentric cat eye. Compared to the traditional adjustable laser oscillator system, the laser oscillator based on a telepentric cat eye structure has the higher alignability and the mobility adjustability, and further improves the stability of the output power. The system can achieve the multi-path simultaneous output. The laser oscillator is convenient to regulate, simple and efficient, and high in practicability.

Description

technical field [0001] The invention relates to the technical field of laser oscillators, in particular to a laser oscillator based on a telecentric cat's-eye structure. Background technique [0002] Optical resonators are an important part of laser oscillators. The function of the optical resonator is to provide the positive feedback of the axial light wave mode and ensure the single mode (or few axial modes) oscillation of the laser. Properly placing two reflectors at both ends of the gain medium constitutes the simplest optical resonant cavity. In the history of laser technology development, the parallel plane cavity was first proposed, which is composed of two parallel plane mirrors. [0003] For laser oscillators with laser resonators composed of plano-planar mirrors, it is very difficult to make the system operate in an absolutely ideal state, because it is very difficult to align the two optical resonator mirrors to be strictly parallel. In addition, the lateral an...
