Abstract. Rate-equation analysis and experiments on a pulsed dual-wavelength Ti:sapphire laser are reported in the paper. A four-energy-level system with two lower-energy levels is put forward and numerical calculations are given. A simple optical setup with two sub-resonators is constructed, which yields a total energy from dual-wavelength lasers up to 41.8 mJ. The largest tunable range is over 1 10nm. Laser characteristics of dual-wavelength pulses are observed. Experimental results are in accord with rate-equation-theory results.

    Broadband terahertz pulses have been generated in 2-cyclooctylamino-5-nitropyridine (COANP) single crystals by optical rectification of 150 fs laser pulses from an amplified Ti:sapphire laser operating at 776 nm. Due to better velocity-matching and a higher figure of merit, COANP allows more...

    Abstract. We have constructed a three-wavelength Ti:sapphire femtosecond laser with an independent tunable wavelength (lambda[sub 1]) and two variable central wavelengths (lambda[sub 2]) and lambda[sub 3]) for use with the multi-excited photosystem II. Stable sub-40-fs pulses are generated. The...
