ELPN 30 ns, 35 mJ, 25 W

Hybrid Erbium Nanosecond Pulsed Lasers

IPG Photonics' hybrid ELPN Erbium crystal q-switched laser provides 25-200 nanosecond pulses at 1.645 μm with pulse energies up to 35 mJ and output powers up to 25 W. The acousto-optically Q-switched Er:YAG head is pumped by IPG's efficient and reliable erbium CW fiber laser. The ELPN pulsed laser addresses non-metal materials processing, scientific and medical applications. Single-frequency option, higher average powers and pulse energies, flat-top beam and other options are available upon request. Please contact IPG Representative with your requirements.
