Maximization of supercontinua in photonic crystal fibers by using double pulses and polarization effects
We show with sub-20 fs pulses both experimentally and theoretically two techniques to control the width and polarization of spectral supercontinua generated in photonic crystal fibers. The first exploits doubl...

Generation of a spectrally asymmetric third harmonic with unamplified 30-fs Cr:forsterite laser pulses in a tapered fiber
Unamplified subnanojoule 30-fs pulses of Cr:forsterite laser radiation are shown to generate the third-harmonic signal in a tapered fiber. Analysis of the dispersion properties of a tapered fiber indicates the...

Two-octave spectral broadening of subnanojoule Cr:forsterite femtosecond laser pulses in tapered fibers
Spectral broadening of femtosecond Cr:forsterite laser pulses is enhanced due to the use of tapered fibers. Supercontinuum generation with unamplified subnanojoule femtosecond Cr:forsterite laser pulses is obs...

Absolute frequency measurement of iodine lines with a femtosecond optical synthesizer
We have used a single laser femtosecond optical frequency synthesizer together with a widely tunable Nd:YAG laser to measure the absolute frequency of several absorption lines in molecular iodine around 532 nm...

Efficient distributed feedback solid state dye laser with a dynamic grating
We present the first operation of a distributed feedback solid state dye laser with a dynamic, pump-induced grating. Broadly tunable, narrow band operation in the region of 616 nm (604–649 nm) has been demonst...
