ELPN-1645-SF Series

Er:YAG Single Frequency Nanosecond Pulsed Lasers

IPG Photonics' ELPN-SF Erbium:YAG single frequency nanosecond pulsed laser provides 10-40 ns pulses at 1.645 μm with pulse energies up to 3 mJ and output powers up to 10 W. The acousto-optically Q-switched Er:YAG head is pumped by IPG's efficient and reliable erbium fiber laser. The Er:YAG-1645-SF pulsed laser addresses lidar remote sensing, range-finding, non-metal materials processing, scientific and medical applications. Higher average powers, pulse energies and other options are available upon request. Please contact your IPG Representative with your requirements.
