All-fiber Tm3+-doped Fiber Laser Using Pump Combiner and Fiber Bragg Grating Inscribed by Femtosecond
All-fiber Tm3+-doped fiber laser can be used as the pumping for (Optical Parametric Oscillator,OPO),realizing 3~5 μm laser output.All-fiber Tm3+-doped fiber laser was demonstrated more excellent application prospects in lidar and electro-optical countermeasure.An all-fiber cladding-pumped Tm3+-doped fiber laser using pump combiner and double-cladding fiber is reported.The pump combiner and double-cladding fiber are home-made.Home-made fiber bragg grating(FBG) is used as reflection cavity.The double-cladding fiber is cooling by water.The fiber Bragg grating is directly written in the Tm3+-doped fiber through 45 fs,800 nm femtosecond and a phase mask.The combiner is used to launch the pump light into the Tm-doped inner-cladding fiber.The wavelength of the laser is about 1.96 μm with a slope efficiency of 37% in respect to the launched pump power,the linewidth is narrow only about 72.4 pm.
