The utility model discloses a tunable brillouin laser in single longitudinal mode broadband. Including optics passive cavity, doping optical fiber amplifier, polarization controller and tunable lightsource, doping optical fiber amplifier includes that the erbium praseodymium of two sections parallel adoption zonation structures that set up mixes optic fibre with tm -doped optical fiber, use the semiconductor laser pumping of different wavelength respectively altogether, and a pair of wavestrip multiplexer and demultiplexer, a gain flattening wave filter, its gain flattening wave filter are located the output of amplifier, doping optical fiber amplifier input/output end sets up the isolator respectively. This tunable brillouin laser in single longitudinal mode broadband simple structure, low cost, output laser is stable. 本实用新型公开了种单纵模宽带可调谐布里渊激光器。包括光学无源谐振腔、掺杂光纤放大器、偏振控制器以及可调谐光源，所述掺杂光纤放大器包括两段并行设置的采用分带结构的铒镨共掺光纤和掺铥光纤、并分别用不同波长的半导体激光器泵浦，对波带复用器和解复用器，个增益平坦滤波器，其增益平坦滤波器位于放大器的输出端，所述掺杂光纤放大器输入输出端分别设置隔离器。该单纵模宽带可调谐布里渊激光器结构简单，成
