home page >> news Back 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 assertion is far from enough, because they need to kn 详情 2023-11-23 Power stability comes standard PreciLasers frequency conversion laser products are new wavelength lasers generated by nonlinear processes such as frequency doubling, sum frequency and difference frequency of fundamental frequency light. In the second-order nonlinear process, since the 详情
