The new green (532 nm) laser LDH-P-FA-530XL generates > 200 mW average output power at 80 MHz repetition rate.
The picosecond pulsed laser diode heads of the LDH-FA Series are based on a Master Oscillator Fiber Amplifier (MOFA) concept with frequency conversion. The master oscillator generates infrared picosecond pulses at variable repetition rates up to 80 MHz (depending on model) using the proven gain-switching technique from PicoQuant. The output of this laser is directly connected to a fiber amplifier, which boosts the output from the seed laser by several dB. This output is then transformed to green emission (531 ± 3 nm) or yellow emission (596 ± 2 nm). The final pulse widths can be as short as 130 ps (FWHM) for the yellow laser head and even < 100 ps (FWHM) for the green laser heads.
