SL300 series lasers are an excellent solution for applications where high energy picosecond pulses are needed. Backward-stimulated Brillouin scattering (SBS), used as pulse compression method, is simple and cost-effective. In addition, SBS compression allows generation of pulses within exceptional duration range: from few nanoseconds to 150 ps.

The new green diode laser ("LDH-P-FA-530") is based on a master-oscillator fibre-amplifier (MOFA) concept with frequency conversion. The master oscillator generates spectral narrow picosecond pulses at 1064 nm at a variable repetition rate from 10 kHz to 80 MHz using the proven gain-switching technique from PicoQuant. The output of this laser is directly connected to a Ytterbium-doped fibre amplifier (YDFA), which boosts the output from the seed laser by more than 10dB. This output is then directly connected to a fibre-coupled SHG waveguide, which converts the infrared laser emission to green emission (531 ± 3 nm) with a very high conversion efficiency. The final output of the LDH-P-FA-530 reaches up to 1 mW average output power at 40 MHz repetition rate. The pulse width is <100 ps FWHM. The laser emits from a FC/APC fibre connector and can be either collimated or directly connected to suited optical fibres. The laser head can be driven by the PDL 828 'Sepia II', the PDL 800-D or the PDL 800-B. The all-fibre setup makes a topology with a several couplings and interfaces completely maintenance-free.

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.
