Diode-pumped semiconductor disk laser

2002 Conference on Optoelectronic and Microelectronic Materials and Devices. COMMAD 2002. Proceedings (Cat. No.02EX601), 2005
Diode-pumped semiconductor disk lasers are based on the principle of diode-pumped solid-state disk lasers. This relatively new type of laser is also referred to as VECSEL (vertical external cavity surface emitting laser). Semiconductor disk lasers show excellent beam characteristics in combination with high output power.

High Power Semiconductor Disk Lasers

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2006
Results on high-power optically pumped semiconductor disk lasers are reviewed. Multi-Watt emission with differential efficiencies larger than 40% and power-densities up to 15 kW/cm2 is demonstrated in the near-infrared wavelength range of 920-1050nm.

DBR-free semiconductor disk lasers

CLEO: 2015, 2015
We demonstrate a novel DBR-free semiconductor disk laser, where multiple quantum well active region is fusion bonded directly onto a diamond heat spreader. CW output powers of 2.5 W have been demonstrated at 1150 nm.

Tailoring the wavelength of semiconductor disk lasers

SPIE Proceedings, 2011
Optically-pumped semiconductor disk lasers (SDLs) represent a proven approach for generation of multi-watt output powers with excellent beam quality [1-6]. They combine many advantages of solid-state lasers with the added benefit of wavelength tailoring provided by the semiconductor gain material.

Visible and ultraviolet semiconductor disk lasers

CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009
Semiconductor disk lasers (SDLs), also known by the alternative name of vertical external cavity surface emitting lasers (VECSELs), have become established in recent years as an attractive new variant in continuous-wave (CW) or quasi-CW “solid state” laser technology [1–3].

Pulsed pumping of a 2.3μm InGaAsSb Semiconductor Disk Laser

2007 Conference on Lasers and Electro-Optics (CLEO), 2007
~1.7 W output power at 2.3 mum is demonstrated from a semiconductor disk laser pumped by a 905 nm high-power pulsed semiconductor laser. The thermal characteristics and wavelength shift are studied over the 100-200 ns pump pulse.

High-power quantum dot semiconductor disk lasers

SPIE Proceedings, 2012
The latest achievements of quantum dot based semiconductor disk lasers are reviewed. Several lasers operating at 1040 nm - 1260 nm were studied. All the structures were grown with molecular beam epitaxy on GaAs substrates. The number of quantum dot layers was varied and the gain was provided either by the ground or the excited state transition of ...
