Abstract

We have analyzed the temporal characteristics of amplified spontaneous emission (ASE) in femtosecond terawatt Ti:sapphire lasers by using a simple method based on fast photodiodes. Instead of measuring ASE directly with fast photodiodes, we created a narrow gap in the spectrum of seed pulses and, after amplification, detected the pure ASE signal through the gap by using a fast photodiode covered with a bandpass filter with high transmission at the gap. Because the detected ASE signal was completely separated from amplified main pulses, preceding and even trailing ASEs could be characterized quantitatively in a single-shot measurement. We believe that our method is a good alternative or a complement to conventional methods for ASE measurements.

Fig. 1

(Color online) Input and preamplified spectra with a gap. The transmitted spectrum through the bandpass filter is displayed together with the ASE spectrum.

Fig. 2
Fig. 2

(Color online) Calibrated ASE signals after the preamplifier with and without the injection of seed pulses. The main pulse is displayed for a synchronized comparison.

Fig. 3
Fig. 3

(a) Calibrated ASE signal after the final amplifier. (b) ASE and short prepulse signals directly measured by the fast photodiode. The short prepulses are identified by the comparison of (a) and (b).

Fig. 4
Fig. 4

(a) Variation of the ASE signal after the final amplifier with respect to the pulse picker's opening time. The numbers are the relative delay of the opening time and the total energy of the ASE, respectively. (b) ASE signal directly measured by the fast photodiode at the same condition as (0 ns, 0 .8   mJ ) in (a).
