摘要：
A hybrid cavity structure based on individual laser diode integrating coherent beam combining （CBC） and spectral beam combining （SBC） is demonstrated.The CBC structure is used to enhance laser output power while optimizing beam quality,and the SBC structure is employed to further increase laser output power.An output power of 1.42 W was obtained at 0.55 A,with a high combining efficiency of 87.2%.Additionally,the brightness of this structure is 58.65 MW·cm-2·sr-1,which is 3.66times that of a single laser diode.The entire structure provides a new approach for increasing the output power and optimizing the beam quality of the laser diode.
