Multimode / 355 nm Wavelength

An innovative laser optics design, combined with an industrial-grade power supply, results in an extraordinarily reliable and rugged diode-pumped Nd:YAG laser for industrial use. A TOTALLY SOLID-STATE LASER for TROUBLE-FREE MANUFACTURING!

  • Efficient diode optical pumping for improved performance and reliability

  • Q-switched pulse stability ≤ 5 % rms peak-to-peak up to 30 kHz

  • Efficient water/water heat exchanger cooling system.

  • Uses intracavity THG assemblies with LBO harmonic generator crystals.

  • “CE Mark” Certified; this is a CDRH Class IV laser product
