0.8W optically pumped vertical external cavity surface emitting laser operating CW at 1550 nm

• An InP based optically pumped vertical external cavity surface emitting laser has been designed and optimised for emission at 1550 nm. To overcome thermal limitations an intra-cavity synthetic diamond heatspreader is bonded to the gain structure. The laser produces 780 mW at -30degreesC and 100 mW at 20degreesC in a near Gaussian beam (M-2 < 1.2).
