Asymmetric waveguide laser diode operated in gain switching mode with high-power optical pulse generation

The performance of a strongly asymmetric waveguide laser diode structure with a relatively thick active layer and low optical confinement factor operated in gain switching mode has been studied experimentally. High-power optical pulse generation in the pulse width regime of ∼100 ps has been demonstrated.

Control of Amplified Optical Parametric Fluorescence in Optical Parametric Chirped Pulse Amplification and High Power Optical Pulse Generation

The amplified optical parametric fluorescence (AOPF) from optical parametric chirped-pulse amplifier (OPCPA) was controlled by injecting a residual fundamental pulse from a seeded Q-switch Nd: YAG pumping laser, as a quenching beam. The output pulse from the OPCPA was used as a seed pulse for Ti: sapphire chirped pulse amplifier (CPA) system to generate over 10TW peak power with a high contrast ratio.
