摘要: The invention is a laser assembly with reduced distortion ripple. The assembly includes a spherical lens for collimating light emitted from the laser. The lens is made of a material which attenuates scattered light which is the source of ripple without appreciably affecting the main beam.

摘要: A technique for characterizing laser chirp utilizes an optical fiber and its inherent interferometric properties. An RF modulating signal is applied to the laser, where the modulated output signal thereafter propagates through a conventional optical fiber. A photoreceiver and spectrum analyzer are coupled to the opposite end of the optical fiber. By adjusting the power of the applied RF signal, the maximum IIN can be determined. The laser chirp can then be calculated by dividing the measurement frequency by the modulation current associated with the maximum IIN value.
