高功率激光二极管放大器
描述：锥形放大器二极管用于放大激光，可以从典型的10mW至50mW直到500mW至1000mW。
High power laser diode ampifier
Tapered Amplifier Diodes are used for amplifiying laser light from typically 10mW .. 50mW up to power values of 500mW ... 1500mW. High power devices are available with up to 0.5W at 740nm and 2W at 980nm
At one side of the laser chip, tapered diode lasers are identical to conventional Fabry Perot lasers. At the opposite side of the laser chip, they are broad area lasers. Inside of the chip, the internal waveguide is tapered for getting a propper matching between both side of the laser chip. Typical geometrical sizes of the laser chip are 2750µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet and the front facet of the laser chip are provided with an anti-reflcetion for avoiding laser action of the tapered amplifiyer itself. There are different versions available. The tapered laser chips are mounted as chip on carrier.
