High-power, diffraction-limited, narrow-band, external-cavity diode laser

Technical Report ·
OSTI ID:5607914
; ; ; ;

We report demonstration of a highly coherent, low-divergence, high-power, external-cavity diode laser suitable for applications such as communications and nonlinear optics that require narrow linewidth in a diffraction-limited beam. Over 1.5 W of cw output power is measured at a wavelength of 856 nm, in a maximum spectral band of 0.02 nm. Greater than 0.1 W of single-frequency power is obtained in a diffraction-limited beam. A simple resonator is used, comprising a multi-element spherical lens and a plane mirror in addition to the diode.
