title: [Measurement of time-dependent spectra excited by pulse laser using multi-fiber delayer and optical multi-channel analyzer].
abstract: A new method and technology for measuring time-dependent spectra excited by pulse laser was reported in the present paper, in which a multi-fiber delayer combined with a two dimensional CCD array detector was employed for collecting and processing the spectra. The multi-fiber delayer consists of five fibers with a length difference of 1-2 m (relative delay time 5-10 ns), and the optical multi channel analyzer is PARC OMA-4. The time-dependent spectra, i. e. the spectra of R6G dye laser, the SRS spectra of acetone, and the plasma emission spectra of metal Mo excited by a double frequency YAG pulse laser with a time resolution of 5 ns were obtained.
