Cross-correlation techniques were employed for direct optical measurement of a Q-switched two-section semiconductor laser output versus electrical bias. Since the switching scheme is not limited by external connections to the device, the ultrafast dynamics of the diode laser can be investigated. In particular, a turn-on delay as small as 70 ps were recorded with picosecond accuracy. In addition, the FWHM and peak power of the Q-switched pulse were also measured. A numerical simulation was performed, and good agreement with experimental results was achieved.
