Abstract :
An experimental study on the emission of THz-radiation from InP1-xAsx and Ga1-xInxAs crystals is reported. The semiconductor materials were grown by a hybrid vertical Bridgman and gradient freezing directional solidification process. A directly diode pumped Ytterbium - and a conventional Titanium-Sapphire femtosecond laser oscillator were used to stimulate the emission of THz radiation from the semiconductor materials. Progress towards compact and cost-effective THz-radiation systems is discussed.
