Confocal unstable-resonator semiconductor laser.

چکیده
GaAs/GaAlAs heterostructure lasers with a monolithic confocal unstable resonator were demonstrated. The curved mirrors satisfying the confocal condition were fabricated by etching. Close to threshold, the lasers operate in a single lateral mode with a nearly collimated output beam. A single-lobe far-field intensity distribution as narrow as 1.9 degrees full width at half maximum was measured.

Excess spontaneous-emission factor in unstable-resonator lasers.
The spontaneous-emission factor in an unstable-resonator semiconductor laser is enhanced by more than 2 orders of magnitude compared with that of a Fabry-Perot semiconductor laser having the same volume. A clear linkage has been observed among the spontaneous-emission factor, the waveguiding property, and the width of the lasing spectral envelope.
متن کاملHigh-Brightness Unstable-Resonator Semiconductor Laser Diodes
High-power high-brightness unstable-resonator edge-emitting semiconductor laser diodes with dry-etched curved mirrors were fabricated and characterized. The epitaxial structure was optimized for high output power operation and consists of a GaAs/AlGaAs gradedindex separate-confinement heterostructure (GRINSCH) with a single 980-nm-emitting InGaAs quantum well. The curved mirrors of the unstable...

Ahstruct-We preseni a formalism for analyzing laser resonators which possdss nonplanar mirrors and iateral waveguiding [e.g., an unstable resonator semiconductor laser (URSL)]. The electric field is expdnded iii lateral modes of the complex-iridex waveguide and is required to rbproduce itself after, one roundtrip of the cavity. We show how the waveguide modes, their gain and loss, and hence the...
متن کاملBeam divergence studies on a long pulse XeC1 excimer
The focusability of a long l)ulse XeCI excimer laser has been improved using confocal positive branch unstable resonators where the outcoupling is done through the convex mirror. For the outcoupler different reflectivity profiles are used. A near diffraction limited output beam is obtained from hard edge unstable resonators. A beam with only one central s1)ot in the focus of a lens can be obtai...
