Abstract

A modified Imacon type streak camera with temporal resolution of 1.5 psec was used for the measurement of pulses generated by a mode locked Er fiber laser operating at 1.55 micron wavelength. The specially developed S1-PV001 image tube had an initial sensitivity of 26 mu A/W at 1.3 micron. To improve the signal to noise ratio for recording low level CW laser radiation additional shutter circuitry was added to the Imacon camera electronics. The camera was operated at 15 Hz repetition rate, triggered by a sample of the RF signal used for driving the acoustooptic mode locker. A very sensitive and simple recording system was used for recording the time dispersed pictures generated in the ICT output screen using a high gain PMT and a 150 micron slit mounted on a translation stage. The signal from the PMT was read with a box car averager and sent to a PC type computer which controlled the translation stage. The acoustooptically mode locked Er fiber laser can generate pulses of 80 psec in CW operation with a peak power of 0.6 W.
