摘要：
The authors describe the fabrication and characterisation of high power, high brightness 1.59 mu m semiconductor lasers for use in surgical applications either directly or as a pump for 2 mu M wavelength Tm-doped fibre lasers. The lasers consist of a novel seven-element tapered waveguide array defined within a chip size of 1mm x 0.5mm. CW output powers in excess of 1.4W at 8A drive current have been achieved and the devices operate with single lobed far field widths of 3.5-4.5 degrees FWHM.
