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 up to 15 kHz

  • Efficient water/water heat exchanger cooling system (self-contained chiller optionally available).

  • Uses Intracavity SHG and THG Assemblies with LBO harmonic generator crystals.

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