PicoQuant GmbH and TOPTICA Photonics AG have jointly developed a new high power picosecond diode laser head for the near infrared wavelength range. The system combines a pulsed seed-laser (PicoQuant's special heads of the LDH Series driven by the PDL 800-B / PDL 800-D / PDL 808 / PDL 828 diode laser drivers) and TOPTICA's tapered amplifier technology in a Master Oscillator Power Amplifier (MOPA) arrangement. The PicoTA produces light pulses shorter than 100 ps at an adjustable repetition rate between 1 MHz and 80 MHz, with amplification of the master laser peak power by more than a factor of 10. Systems are available at 730, 780, 980 and 1060 nm.
An additional second-harmonic generation module to provide laser pulses in the cyan and green spectral range at 490 and 530 nm is also available.

Scheme of the PicoTA setup - a picosecond diode laser of the LDH Series is used as a seed for a tapered amplifier. Optional, a SHG crystal is added to double the emission frequency.
