Er:YAG Nanosecond Pulsed Lasers Typical output energy vs pump power characteristics for different repetition rates for low (0.01-2 kHz shown in red) and high (2-100 kHz shown in black) rep rate modifications Applications LIDAR/Remote Sensing Medical Applications Track Illuminator Material Processing Range Finder Features Output Power up to 25 W Variable Pulse Width Option Energy Amplification Option Single-frequency Option Repetition Rate 0.01 -100 kHz IPG Photonics' 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's 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. Please contact your IPG Representative with your requirements.
