## Abstract The generation of supercontinuum spectra from the injection of femtosecond pulses into microstructure or tapered fibers has now been achieved by several groups [1, 2]. In 2001, we generated a supercontinuum around 1.55 Β΅m by injecting a 100βfsβduration fiber laser pulse with a 1βnJ puls
Temperature effect on the diffraction efficiency of the liquid crystal spatial light modulator is investigated. The birefringence of the liquid crystal as functions of the temperature is measured with and without the power supply. It is shown that the birefringence reduces while the temperature incr
