Abstract

A diode laser source with a continuous wavelength (CW) power of 106 W and the beam quality M² of 14.6 is demonstrated by spectrum beam combining (SBC) of three 800 nm LDAs. With the help of relay optics, a wavelength interval of 0.21 nm and a whole spectrum span of 13.9 nm are achieved, which is almost 10 times narrower than those of the structure without the relay optics. This presents a method to obtain a high power and high beam quality SBC laser source with a narrow spectrum.
