The paper proposes and numerically demonstrates a simple and efficient broadband frequency-tripling scheme for Nd:glass laser system based on mixing narrowband and broadband laser pulses in the sum-frequency generation (SFG) process. The group-velocity mismatching effect in the of SFG process is substantially alleviated with the assist of a narrowband laser, which is the dominant obstacle to efficient broadband third-harmonic generation. Moreover, by adding a second tripler in the SFG process, the proposed scheme will support efficient frequency tripling over a bandwidth of 5 nm (theoretical efficiency more than 80%).
