一种风速仪用761nm1592nm3184nm1411nm六波长激光器
摘要：
一种风速仪用761nm1592nm3184nm1411nm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λXⅠ3184nm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ⅡλlⅡ1411nm的光学参量振荡器1，总体构成761nm、490nm、1592nm、980nm、3184nm、1411nm六波长光纤激光器。
摘要（英）：

The invention provides a 761 nm/1592 nm/3184 nm/1411 nm six-wavelength fiber laser for an anemoscope. A resonant cavity is set to be a triangular and annular optical fiber laser cavity. Deep-etching optical fiber reflectors are arranged at the four corners of the triangular and annular optical fiber laser cavity. A periodically poled lithium niobate four-wavelength frequency-mixed laser resonant cavity, with the signal light thereof to be lambda XI 3184 nm in wavelength, is arranged at the middle position of an upper light path. A frequency-doubled cavity I, with the frequency-doubled light Ilambda BI thereof to be 490 nm in wavelength, is arranged at the middle position of a left light path. An optical parametric oscillator 1, with the idler light II lambda 1II thereof to be 1411 nm in wavelength, is arranged at the middle position of a right light path. In this way, the above parts together form the 761 nm/490 nm/1592 nm/980 nm/3184 nm/1411 nm six-wavelength fiber laser.
