AlGaAsSb/InGaAsSb single-quantum-well (SQW) laser diodes emitting at 2 μm were fabricated and tested. At 10–15 °C, the uncoated SQW lasers with 2–3 mm cavity lengths exhibit a threshold current density of 115 A/cm2, a continuous-wave output pow

We report emission of a 100 mM cw beam into a nearly-diffraction-limited spot by a grating surface emitting (GSE) laser. The distributed out-coupled master oscillator power amplifier (DOC-MOPA) produces monochromatic (933 nm) narrow linewidth (10 MHz

Broadening the waveguides of 2 μm AlGaAsSb/InGaAsSb separate‐confinement multiquantum‐well lasers decreases their internal losses to 2 cm−1, while threshold current densities remain as low as 300 A/cm2. The consequently high cw differential ef

We describe room‐temperature 2.78 μm AlGaAsSb/InGaAsSb multiquantum well lasers. Pulsed laser operation was observed at 15 °C with a threshold current of 1.1 A (10 kA/cm2), and a maximum power output of 30 mW, and a maximum differential quantum e

Calculation of the optical field distribution in 2 micrometer AlGaAsSb/InGaAsSb/GaSb multiple quantum well (MQW) lasers shows that incorporation of about 100 nm waveguide layers between quantum wells (QW) and cladding layers increases the optical con

Continuous and quasi-continuous wave operation of 2.7-μ InGaAsSb/AlGaAsSb multi-quantum-well (MQW) lasers was demonstrated up to a temperature of 234 K (-39°C) and 253 K (-20°C), respectively. These devices were grown by molecular-beam epitaxy (MB

Monolithic fanned-out amplifier lasers (acronym: FOAL), are capable of producing high optical power, greater than 1 watt. They operate single wavelength and can be collimated to generate a nearly Gaussian beam useful for applications requiring an ine
