There are many factors that cause unstable output radiation of green DPSS lasers. For example, beam stability may be affected by many factors such as mechanical structure of unstable resonator, operating temperature change, thermal lens effect, pump light source power fluctuation, absorption of green light laser crystal, mode hopping There is. Try a number of ways to guarantee the high performance of 532 nm green DPSS laser.
In various high-tech scientific studies, continuous and pulsed green lasers can satisfy the majority of applications. However, the green DPSS laser system always requires high output stability in special work fields such as laser light fluorescence, light absorption, light scattering method and precision measurement. As a result, laser engineers are very important to pay attention to the development and research of high quality lasers.
