2.0um Band QCW Fiber Laser



Connet 2.0um band series high power QCW fiber laser adopts MOPA structure design. By optimizing the pump power and gain fiber length of the amplifier, and properly coiling the fiber, the output power is improved while obtaining the best beam quality without distorting the pulse. Under the condition of millisecond (ms) long pulse operation, the nearly ideal square wave pulse output is guaranteed. MOPA structure design achieved narrow spectral width output (<0.7 nm) and near diffraction limit output beam quality.
