Optically In-Well-Pumped Semiconductor Disk Laser With Low Quantum Defect
An in-well pumped InGaAs disk laser emitting at 984 nm is presented. The device is designed to eliminate major loss mechanisms attributed to heat generation in semiconductor disk lasers. An output power of close to 7W at room temperature is achieved by optical excitation with a fiber-coupled 940 nm diode laser. Strong cooling or the use of heat spreaders with high thermal conductivity is not ne...
متن کاملDesign of a new asymmetric waveguide in InP-Based multi-quantum well laser
Today, electron leakage in InP-based separate confinement laser diode has a serious effect on device performance. Control of electron leakage current is the aim of many studies in semiconductor laser industry. In this study, for the first time, a new asymmetric waveguide structure with n-interlayer for a 1.325 μm InP-based laser diode with InGaAsP multi-quantum well is proposed and theoreticall...
متن کاملLaser-induced quantum coherence in a semiconductor quantum well.
The phenomenon of electromagnetically induced quantum coherence is demonstrated between three confined electron subband levels in a quantum well which are almost equally spaced in energy. Applying a strong coupling field, two-photon resonant with the 1-3 intersubband transition, produces a pronounced narrow transparency feature in the 1-2 absorption line. This result can be understood in terms ...
متن کاملSemiconductor quantum-well saturable absorbers for efficient passive Q switching of a diode-pumped 946 nm Nd:YAG laser.
InGaAs quantum wells and a Bragg mirror structure are grown on a GaAs substrate to simultaneously serve as a low-loss saturable absorber and an output coupler for highly efficient Q switching of a diode-pumped Nd:YAG laser operating at 946 nm. With an incident pump power of 9.2 W, the laser produces pulses of 38 ns duration with average pulse energy of as much as 20 microJ at a pulse repetition...
متن کاملBessel-beam-pumped tunable distributed-feedback laser.
A distributed-feedback (DFB) dye laser that is pumped by a standing Bessel-beam wave is constructed. Because of the long line focus of the Bessel beam, the laser medium is pumped in only a very thin filament (a few micrometers) along the optical axis. At the same time, longitudinal-mode selection is achieved because of the DFB effect. It is demonstrated that when the effective wavelength of the...
