Research Abstract

The purpose of the research project is divided into two items. One is to find a simple method to get ultrashort laser pulses by using commercially available conventional diode lasers. And the other is to develop a new technique of ultrafast spectroscopy by using semiconductor optical devices. Summary of the results are as follows: 1. We could apply good anti-reflection coatings to the output facets of laser diodes. 1. Mode-locking oscillation was obtained in an external cavity by using the anti-reflection coated laser diode. The pulse width, pulse energy and the repetition rate were 10 ps, 10 pj and 100 MHz, respectively. 1. The output of the above mentioned picosecond diode laser (pulse width 30 ps, pulse energy 10 pJ) was amplified by using a dye cell amplifier excited by the second harmonic light of a Q-switched YAG laser. The amplification of about 10^6 was obtained, and the pulse width, pulse energy and repetition rate of the output were 40 ps, 40 uJ and 1 Hz, respectively. 1. We showed that multi-mode diode lasers and superluminescent diodes can be used as the excitation light source for incoherent light photon echo experiments. 1. We succeeded in observing accumulated photon echoes for the first time by using a non-laser light source, a normal type light emitting diode. The use of non-laser light source will extend the photon echo experiment into the wavelengthregions where lasers are not presently available.
