Abstract

A directly diode-pumped amplifier system (10) is disclosed which produces sub-picosecond pulses with an output power of 2 watts or more. Computer resources (22) are coupled to the amplifier system and are configured to provide control of operating parameters of the amplifier system. An optional second harmonic generator (19) is supplied to increase the contrast ratio and reduce the minimum focal spot size. This amplifier system can be utilized for material processing applications.
