Home page >> News 返回上一步 2023-11-23 Will fiber amplifiers broaden the linewidth? In order to obtain higher power lasers of different wavelengths, or to use higher power lasers for nonlinear frequency conversion, we usually use fiber amplifiers for power amplification. However, many users have extremely high requirements for the line w 详情 2023-11-23 Is the line width after frequency doubling twice that of the fundamental frequency light? Theoretically, the width of the doubled frequency light is twice that of the fundamental frequency light, so its frequency stability remains unchanged. For scientists studying ultra-stable lasers, this statement is far from enough, because they need to kn 详情 2023-11-23 Power stabilization function Precilasers frequency conversion laser products are new wavelength lasers generated by fundamental frequency light through nonlinear processes such as frequency doubling, sum frequency and difference frequency. In the second-order nonlinear process, since 详情
