ELPN-1617/1645
Product Description
ELPN Erbium:YAG nanosecond pulsed laser provides
25-200 ns pulses at 1.645 μm with pulse energies up
to 35 mJ and output powers up to 25 W. Low and high
repetition rate modifications operate over 0.01-2 kHz
and 2-100 kHz frequency ranges, respectively. The
acousto-optically Q-switched Er:YAG head is pumped
by IPG efficient and reliable erbium fiber laser. The
Er:YAG-1645 pulsed laser addresses lidar remote
sensing, range-finding, track illumination, materials
processing, marking, resistor trimming, as well as
scientific and medical applications. Higher average
powers, pulse energies and other options are available
upon request.
