Description

technical field [0001] The invention relates to the field of optoelectronics and laser technology, in particular to a tunable ultra-high repetition frequency optical parametric oscillator, which can tune the output wavelength of solid-state and diode lasers as required. It is suitable for precision optical measurement, spectroscopy, lidar, environmental pollution gas detection, medical optics and other fields. Background technique [0002] The energy level structure and fluorescence emission lines of the laser medium play a decisive role in which wavelength of laser light can be produced. Different laser media can produce laser light of different wavelengths, but in most cases, a laser using a single laser medium can only output laser light of a specific wavelength. However, from basic research in physics and chemistry to medicine and even industrial applications, more and more research or application fields require the simultaneous use of two laser beams with different wav...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the use of dyes as the excitation medium, when the laser frequency is high or the energy is too strong, the dye absorbs energy to saturation and is easy to boil, resulting in a significant decrease in the uniformity, energy and stability of the output spot, and a sharp shortening of the life of the dye. The dye needs to be replaced frequently, so the laser frequency and energy applicable to the dye laser are relatively low

[0006] 2. The overall wavelength tuning range of the dye laser is different according to different dyes. The tuning range of the output wavelength of each dye is very limited, and the dye pool needs to be cleaned first when replacing the dye. It is very cumbersome to operate when a large range of wavelengths is required for initial research.

[0007] 3. The dyes are toxic to a certain extent, so you need to pay attention to safety during operation

The main disadvantages include that this optical parametric oscillation system uses optical fiber to compensate for dispersion, which is not suitable for application to ultra-high repetition rate and high-energy pump laser systems
