The invention is a laser assembly for reducing distortion ripple. The assembly includes a spherical lens which has a portion of its surface made optically asymmetric to prevent multiple reflections of scattered light within the lens.

Analog laser assembly

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.

Semiconductor laser assembly with reduced ripple

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.
