Operation of a dynamically stabilized surface-emitting AlGaAs channeled-substrate-planar large-optical-cavity distributed Bragg reflector laser with a 0.25/sup 0/ x 8/sup 0/ far-field pattern is reported. With 50% duty cycle and 50 ns--2 ms pulse length operation at room temperature, thresholds as low as 150 mA were obtained. No side modes were observed to 40 dB below the principal wavelength intensity under 100% modulation depth operation.
