The requirement of less-expensive laser system for nonlinear bio-imaging applications can be addressed employing chip-sized devices. Preliminary studies using an amplified quantum-dot laser system show its potential to be used for such applications.
A tunable master-oscillator power-amplifier (MOPA) picosecond optical pulse source using all chirped quantum dot (QD) structures is demonstrated (60nm tunability). Under fundamental mode-locked operation, the highest peak power of 4.39 W is achieved.
We present λ=1.26 μm all quantum-dot (QD) master-oscillator-power-amplifier (MOPA) system with a pulse energy of 321 pJ, and peak power of 30.3 W at a repetition rate of 648 MHz for nonlinear bio-imaging applications.
Summary form only given. Recently, SDL Inc. integrated several amplifiers in a parallel way to get a diode master oscillator power amplifier (MOPA) array with a coherent laser output. In this presentation we propose and demonstrate a diode laser MOPA system using photorefractive multibeam coupling to combine amplifiers in phase.
