Power Supply and Current Modulation Circuits for Semiconductor Lasers
Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

متن کاملNovel ultrafast semiconductor lasers
Novel ultrafast semiconductor lasers Ursula Keller ETH Zürich SESAM modelocked VECSELs and MIXSELs are attractive semiconductor laser sources that deliver ultrashort laser pulses with picosecond and femtosecond pulse durations in combination with watt-level average output power levels in the gigahertz repetition rate range. The excellent beam quality and low-noise performance makes them highly ...
متن کاملDynamics of Multisection Semiconductor Lasers
We investigate the longitudinal dynamics of multisection semiconductor lasers based on a model, where a hyperbolic system of partial differential equations is nonlinearly coupled with a system of ordinary differential equations. We present analytic results for that system: global existence and uniqueness of the initial-boundary value problem, and existence of attracting invariant manifolds of l...
