We report the ultrafast operation of a light-controlled optical-fiber modulator, driven by subpicosecond, compressed, and amplified (6000 Ã…) dye laser pulses, controlling frequency-doubled (5320 Ã…) yttrium aluminum garnet laser pulses. The operation of the modulator is based on the optical Kerr effect, and its main component is 7 mm of single-mode optical fiber. Using this system as a light-controlled shutter, we produced either 0.4 ps green light pulses or 0.5 ps holes on the much longer duration second harmonic pulses.

    Abstract. The spectral and temporal processes in broadband pulsed-laser emissions of near-infrared dyes generated from low-Q and short laser cavities have been investigated with a rate equation model extended to a multiwavelength analysis. A very fast spectral evolution is proved, and this leads...

    The unique torsion characteristics of the CO2-1aser-induced LPFG depend strongly on the length of the twisted fibre. While the LPFG is much shorter than the twisted fibre, its resonant wavelength and amplitude change wavelike with the twist-rate applied. In addition, the shift of the resonant...
