nd:ylf lasers
Based on Quantronix’s proven Darwin laser series, the Darwin-Duo
is a dual oscillator/single head, high repetition rate, diode-pumped
Nd:YLF laser. The Darwin-Duo offers the ultimate in flexibility for PIV
and other dual output applications.
Darwin-Duo Series
527 nm
The combination of two independent oscillators allows complete
control of pulse separation and pulse energy. Both oscillators in the
Darwin-Duo are identical in optical design giving temporally and
spatially matched pulses for the highest degree of cross-correlation
possible. Each oscillator can be independentally triggered via TTL
inputs. As an option, a compact, external combination box can be
directly attached to the laser to make access to the beam
combination optics easier and safer for the rest of the laser system.

The Darwin-Duo uses our patented* intracavity frequency
doubling to achieve high energy 527 nm outputs without
resorting to the tight focusing (which can result in optical damage)
necessary for extra-cavity doubling. Our patented* pumping chamber
design increases the overall efficiency allowing for high pulse energy,
excellent beam quality and long component lifetimes from a compact
diode-pumped package.
