Problems solved by technology
However, there is currently no experimental system specially designed for the teaching experiment of optical parametric oscillators. The existing experimental instruments are either packaged commercial products that cannot show students the internal structure of optical parametric oscillators, or teaching staff The principle prototype built by oneself is complicated to operate, and the adjustment is extremely time-consuming. It is difficult for students to complete the experimental operation within the experimental class hours.
Lack of an intuitive and easy-to-operate experimental platform makes it difficult to carry out teaching experiments

The invention discloses an experimental system of a pumping OPO (optical parametric oscillator) of a YAG pulse laser. The experimental system comprises a light condensation cavity component, a Q-modulation component, a mirror component, an OPO conversion component, a second output mirror, a double-frequency mirror component and a target plate component on the same optical axis. The light condensation cavity component, the mirror component and the second output mirror form a resonance cavity of the YAG laser and form laser oscillation in the same after electrified, the Q-modulation component is used for enabling the YAG laser to output short pulse laser light intensive in energy, a resonance cavity of the OPO is formed in the OPO conversion component used for generating laser oscillation of appointed optical parameters in the resonance cavity of the OPO and outputting laser light, and the double-frequency mirror component is used for converting the laser light into green or red light distinguishable for human eyes; the target plate component is used for displaying the green or red light. The experimental system is modularized and is simple to operate and convenient for students to learn the structural composition and the operating principle of the OPO.
Description
technical field [0001] The invention relates to the field of teaching experiment systems, in particular to an experiment system in which a YAG pulse laser pumps an optical parameter oscillator. Background technique [0002] Optical parametric oscillation (OPO) technology can generate wide-spectrum tunable coherent light output, and can convert existing laser wavelengths to bands that traditional lasers cannot reach. It is used in military countermeasures, atmospheric environment monitoring, lidar and spectroscopy research. It is widely used in many fields, and it is an important frequency tuning technology that students majoring in optoelectronics need to understand and master. [0003] In order to allow students to better learn the relevant knowledge of optical parametric oscillators, it is necessary to allow students to intuitively learn and understand the structure, composition and working principle of optical parametric oscillators through experimental means. However, t...
