抽运波长对连续单频Nd∶YVO4激光器输出特性的影响
Influence of Wavelength of Pump Source on Output Power of 1064 nm Laser
摘要
实验研究了抽运源抽运波长对激光器输出功率的影响。当抽运源的抽运波长为808 nm 时,单频1064 nm 激光的输出功率最高只有20 W,而当抽运源的抽运波长为888 nm 时,单频1064 nm 激光的输出功率可以提升至33.7 W。通过在腔内插入倍频晶体引入非线性损耗,激光器实现了稳定的单纵模运转。激光器的长期功率稳定性优于± 0.51% ,M2因子优于1.1。
Abstract
The influence of pump wavelength on output power of 1064 nm laser is experimentally investigated. When the wavelength of pump source is 808 nm, the maximal output power of laser is only 20 W. However, when the wavelength of pump source is 888 nm, the maximum output power of 1064 nm laser can reach up to 33.7 W. In that case, the laser can work with single-longitudinal-mode owing to the nonlinear loss induced by the frequency doubling crystal in the resonator. The measured long term power stability and M2 are better than ±0.51% and 1.1, respectively.
