Paper Abstract

Measurements of the simultaneous pulse response of the individual modes of high power laser diode arrays and broad-stripe laser diodes are presented in this paper. The modes of AlGaAs laser diodes were dispersed with an echelle grating and individually imaged onto a scanning avalanche photodiode (APD) and alternately a streak camera. Considerable power sharing over a period of 60 ns was observed among the modes of these lasers. Experimental conditions were varied and it was found that both the modulation depth and bias current had a considerable effect on the severity of the modal transients. The experimental modal transients were compared to theoretical values obtained using a finite element code to simulate temperature transients in the active area of the lasers.
