A Picosecond laser generates ultrashort pulses which are generally defined as <50 ps (x10-12 s). In a Thin Disk system the laser amplified is based on a Thin Crystal Disk rather than the more common cylinder.  This geometry provides enhanced beam quality due to better thermal management and hence minimised thermal lensing effects. This type of laser is typically utilised for laser ablative machining where a reduced Heat Affected Zone (HAZ) is required.

The Trumpf TruMicro 5050 is a Diode Pumped Picosecond laser based on Thin Disk technology. The laser produces high beam quality  combined with high average power of 50 W.
