Abstract

We present the design, technology and performances of single-frequency GaAs-based electrically-pumped quantum-well vertical external-cavity surface-emitting lasers. We report on room-temperature continuous-wave laser emission at 1 μm with 10 mW output power. The external cavity provides a circular TEM₀₀ beam close to diffraction limit (M² = 1.2). The laser exhibits single frequency operation (<; 30 MHz), a side mode suppression ratio >; 37 dB and linear light polarization (>; 20 dB). Thermal, electrical and optical properties of the device are studied.
