Generation of 30ps pulse from a short cavity dye laser pumped by a copper bromide laser

The transient phenomena of output from a short cavity dye laser (SCDL) pumped by a copper bromide laser are investigated. For the first time a 30ps dye laser pulse was generated, using the SCDL with Rh6G and DODCI dissolved in ethanol.

Measurement of Long-Pulse Fine Structure by Time-Spectrum Coding

We propose and numerically simulate a time-spectrum coding method to measure the fine structure of long pulses. By a difference-frequency (DF) interaction between the pending-measured long pulse and a linearly chirped pulse, the spectrum of the generated DF pulse contains the intensity information of the pending-measured pulse and the frequency information of the linearly chirped pulse. The numerical simulation results show that the fine structure of the pending-measured pulse can be derived from the spectra of the DF pulse and the linearly chirped pulse.

Amplification of tunable high repetition picosecond pulse from short cavity dye lasers

It is reported here that synchronous amplification and tuning of 30ps pulses from the short cavity dye laser pumped by copper bromide laser have been achieved by a dye amplifier-dispersion system. It can be tuned continuously from 570 to 590nm to be almost Fourier-transform limited when using Rh6G solution.
