摘要
研制出一种1061 nm和1064 nm双波长连续输出的Nd∶YAG微片激光器。通过对激光器输出端所镀膜系的透过率进行设计,平衡了1061 nm和1064 nm激光的阈值泵浦功率;以激光二极管(LD)作为泵浦源,在室温下对3组不同厚度的工作物质分别进行了实验,均得到了1061 nm/1064 nm双波长激光输出。采用在微片状晶体两端直接镀膜形成谐振腔的方式,压缩了谐振腔的光学长度,在双波长输出的同时实现了1064 nm波长下的多纵模输出。
Abstract
In this study, a 1061 nm/1064 nm dual-wavelength Nd∶YAG microchip laser is developed. By designing the transmission curve of the thin film coating at the output end of the laser, the threshold pump powers of 1061 nm and 1064 nm lasers are balanced. Using diode lasers as pump source, three groups of working materials with different thickness are tested at room temperature, and the 1061 nm/1064 nm dual-wavelength outputs are observed. The optical length of the resonator is compressed by directly coating the two ends of the microchip crystal to form a resonator. Simultaneously, the multi-longitudinal mode output at a wavelength of 1064 nm wavelength is realized.
