We present the design, technology and performances of single-frequency GaAs-based electrically-pumped quantumwell 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.
