Simultaneous dual-wavelength generation from vertical external-cavity surface-emitting semiconductor lasers

This is the authors' abstract. We don't add key points for this paper.

We demonstrate dual-wavelength emission from optically pumped vertical-external-cavity surface-emitting lasers (VEC-SELs) with two different gain mirror designs. The first gain mirror design (S1) generated an optical output power of 0.39 W at S = 984 nm and 0.30 W at L = 1042 nm. A VECSEL using the second gain mirror design (S2) generated a maximum optical output power of 0.75 W at S = 966 nm and 1.38 W at L = 1047 nm. VESCELs using either gain mirror design exhibited self-pulsating behaviour in the high output power regime. In the VECSEL using the S1 gain mirror design, self-pulsation started beyond the S output power of 140 mW and L output power of 115 mW. The corresponding output power limits in the VECSEL using the S2 gain mirror were 300 mW for both wavelengths.
