MNL1342

DIODE PUMPED NANOSECOND PASSIVELY Q-SWITCHED LASER

MNL1342 series DPSS passively Q-switched short pulse nanosecond laser designed for industrial and medical needs like OLED repair, photo-acoustic, etc., deliver high peak powers at 1000 Hz repetition rate. Innovative laser cavity and harmonics unit with stabilized temperature control delivers stable output parameters. Small footprint is welcome point for integration into OEM systems. Short nanosecond pulse duration of < 2 ns, high pulse energy more than 100 µJ, high repetition rate from up to 1000 Hz covers broad range of applications where 1.3 µm wavelengths are needed.

Standard optional harmonics to red (671 nm) and blue (447 nm, 336 nm) is available.
