High Power Semiconductor Disk Lasers

2005 Pacific Rim Conference on Lasers & Electro-Optics, 2005
We present high-power emission from semiconductor disk lasers. By intra-cavity frequency-doubling of multi-Watt infra-red emission, more than 0.6 W of blue and green have been generated. 200 mW have been achieved directly for red emitters.

290-fs pulses from a semiconductor disk laser

Optics Express, 2008
Transform-limited pulses as short as 290 fs at 1036 nm are generated by a diode-pumped semiconductor disk laser. The all-semiconductor laser employs a graded-gap-barrier design in the gain section. A fast saturable absorber mirror serves as a passive mode-locker. No further elements for internal or external dispersion control are required.

Array-Format Microchip Semiconductor Disk Lasers

IEEE Journal of Quantum Electronics, 2008
We report a detailed study of an array-format 1.055- mum microchip semiconductor disk laser which uses a microlens-patterned diamond both as an array of stabilizing output coupling mirrors and a heatspreader. A thermal study of the devices, using a finite element analysis, is carried out and confirms the thermal management capabilities and power ...

Quantum dot semiconductor disk laser at 13  μm

Optics Letters, 2015
We present a semiconductor disk laser (SDL) emitting at the wavelength of 1.3 μm. The active region of the SDL comprises InAs quantum dots (QDs) that are embedded into InGaAs quantum wells (QWs). An output power over 200 mW is obtained at 15°C, which represents the highest output power reported from QD-based SDLs in this wavelength range.

Quantum-dot semiconductor disk lasers

Journal of Crystal Growth, 2008
Abstract We demonstrate quantum-dot (QD)-based, optically pumped semiconductor disk lasers (SDLs) for wavelengths ranging from 950 to 1210 nm. QDs grown either in the submonolayer (SML) or in the Stranski–Krastanow (SK) regime are employed as active layers of the SDLs which are based on two different design concepts.

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.
