Abstract

Summary from only given. We have developed a real industrial femtosecond system with performances fitting the requirement for real world applications. This Yb:KGd(WO/sub 4/)/sub 2/ (KGW) system produces 150 /spl mu/J, 420 fs pulses at multi-kilohertz repetition rates. It uses only one 2 W diode for the oscillator and one 15 W diode for the amplifier, and exhibits excellent short and long term stability. We think that reliable rugged femtosecond lasers will open the path for a large range of applications that present technologies based on Ti:sapphire cannot reach.
