Abstract
Surface-emitting distributed feedback (SE-DFB) diode lasers possess many advantages compared to edge emitters, in terms of power, brightness and spectral characteristics. We have demonstrated 312 W and 68 W of peak power at 1-μs pulse duration and 100-Hz repetition rate from single 97x nm SE-DFB laser chips with electrically-pumped stripe of 3.75 mm2 and 0.18 mm2 respectively, achieving a power density of 378 W/mm2. Under the same pulsing condition, we have also demonstrated current-limited 206 W of peak power out of a 100 μm / 0.22 NA fiber with only two 2x1 chiplevel SE-DFB laser arrays.
