Green Picosecond Pulsed Laser Diode Heads - LDH-P-FA-530

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 40 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. A high power version ("LDH-P-FA-530B") with up to 2 mW average power at 40 MHz repetition rate is also available. 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.
