Nonlinear Optics: Materials, Fundamentals and Applications (2007), paper MD4 | 2007

We observed strong self-phase-modulation of over 20π inside self-pulsating laser diodes. We found that this phenomenon plays a crucial role in reducing noise when using a semiconductor laser to read information from an optical disk.

We demonstrate the generation of 20W peak power, 3ps optical pulses using a combination of a GaInN-based, mode-locked laser diode and an optical amplifier. A strong nonlinear phase shift over 4π has also been observed.
