- We have developed successfully a laser pulse multi-pass amplifier based on Chirped-Pulse Amplification (CPA) technique for femto-second titan-sapphire laser pulses. This amplifier was pumped at 532 nm at 10 Hz by a high power Nd:YAG laser. The amplifier was well combined with: A pulse selector which selects single laser pulses at 10 Hz from the mode-locked femto-second titan-sapphire laser pulses of 80 MHz; A single grating (1200 graves/mm)-based pulse stretcher. This stretcher of a horizontal beam size of 4 cm on a grating surface well stretched single laser pulses of 85 fs (at 800 nm and 10 Hz) to 72 ps corresponding to a large stretching factor. A single grating (1200 graves/mm)-based compressor which works in a similar way to the pulse stretcher or compressor using a pair of gratings and well compressed single amplified laser pulses of 72 ps to 85 fs. In energy, this multi-pass CPA amplifier has been successfully used for amplifying pulse energy of femto-second titan sapphire laser pulses from 10 nJ to 70 µJ, corresponding to a factor of 7000.
- Applications of ultrashort pulse to investigate non-linear optical effects & spectroscopy.
- Trained 03 Master students in optics & laser physic (defended in 2016) and 01 PhD student (will be defended in 2017).

- The fist time in Vietnam, a laser pulse multi-pass amplifier based on the CPA for femto-second Titan-sapphire laser pulses have been successfully developed.
- Contribute to improve the training quality for Master and Ph.D students and researchers at the Institute of Physics, VAST.
- Expanding scientific cooperation with important partners in the field of laser and photonics in order to open good chance for technology transferring, scientific training and research
