High-power, high-brightness, index-guided tapered lasers, comparison between CW and pulsed operation
17 June 2007
Index-guided tapered lasers at 975 nm deliver 1 W CW, with a low M2 of 1.6 at 1/e2, which is a record for such a device, no measurable astigmatism, and a narrow far-field angle of 6.8deg FWHM.
