Abstract :
Wavelength stabilised 808 nm broad area distributed feedback (DFB) diode lasers with high continuous-wave (CW) output have been realised. The centre wavelength was locked at the Bragg condition with narrow spectral widths of 0.3 nm FWHM and shifted at a rate of 0.062 nm/degC. The 2 mm long laser showed a record high 57 wall-plug efficiency and more than 4W CW output power at 25 C heatsink temperature. It is an ideal source for pumping solid-state lasers such as Nd-doped YAG and YVO4.
