一种风速仪用728.2nm490nm1424nm六波长激光器
摘要：
一种风速仪用728.2nm490nm1424nm六波长激光器，谐振腔设置为三角形环形光纤激光腔，在三角形环形光纤激光腔的四个角上设置深刻蚀光纤反射镜，在上边光路的中间位置设置信号光λXⅠ2848nm波长周期极化铌酸锂四波混频激光谐振腔，在左边光路的中间位置设置倍频光ⅠλBⅠ490nm的倍频谐振腔Ⅰ，在右边光路的中间位置设置闲频光ⅡλlⅡ1493nm的光学参量振荡器1，总体构成728.2nm、490nm、1424nm、980nm、2848nm、1493nm六波长光纤激光器。
摘要（英）：

The invention discloses a six-wavelength laser of 728.2nm, 490nm and 1424nm for an anemograph. A resonant cavity is set as a triangular annular optical fiber laser cavity, optical fiber reflectors aredeeply etched on four corners of the triangular annular optical fiber laser cavity, a signal light lambda 2848nm wavelength periodically-polarized lithium niobate four-wave mixing laser resonantcavity is arranged at a middle position of an upper optical path, a frequency doubling resonant cavity I with frequency doubling light I lambda 490nm wavelength is arranged at the middle positionof a left optical path, an optical parametric oscillator 1 with idle frequency light II lambda 1493nm wavelength is arranged at the middle position of a right optical path, thereby totally forming the six-wavelength optical fiber laser of 728.2nm, 490nm, 1424nm, 980nm, 2848nm and 1493nm.
