Abstract
A three-end-output 532 nm and 1064 nm and 808 nm three-wavelength optical fiber laser device for a wind-velocity indicator is disclosed. According to the three-wavelength optical fiber laser device, 808 nm pump light emitted through a multi-mode pump diode module group is coupled to a double end output transmission optical fiber through a coupler, and then the pump light is output through two ends. A left path is characterized in that after the pump light passes through a left optical fiber coupler, 1064 nm photons are irradiated in a pumped manner and are amplified in a left optical fiber resonant cavity, then a 1064 nm laser is output through two ends. At one end, the 1064 nm laser passes through a KTP crystal and then generates a frequency multiplication light which is 532 nm in wavelength. At the other end, the 1064 nm laser passes through two beam expanding lenses and output lenses, and then the 1064 nm laser is directly output. Therefore 532 nm and 1064 nm lasers are formed. A right path is characterized in that the pump light passes through an 808 nm output lens, and therefore an 808 nm laser is directly output. Thus, three-wavelength 532 nm and 1064 nm and 808 nm lasers are output through three ends of the left and right paths.
