To achieve beam combining, we employ Lyot-filtered optical reinjection from an external cavity, which forces lasing of the individual diode laser bars on intertwined frequency combs with overlapping envelopes and enables a high optical coupling efficiency. Unlike other spectral beam combining techniques that are based on the use of grating elements, this technique is insensitive to the thermal drift of the laser diodes. In addition to this, the FWHM spectral width at 1 kW output power is only around 7 nm, which is convenient for wavelength sensitive applications such as pumping.<\/p>\r\n\r\n\r\n\r\n [1] Crump, P., Wenzel H., Erbert G., and Tr\u00e4nkle G., \u201cProgress in increasing the maximum achievable output power of broad area diode lasers,\u201d SPIE Proc.
