Multimode / 1064 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 or scientific use.


Efficient diode optical pumping for improved performance and reliability
High power visible output from small diameter, low divergence beam
Highly circular multimode beam profile
Q-switched pulse stability:  5 % peak-to-peak up to 10 kHz
Efficient water/water heat exchange cooling system (water-cooled, refrigerated-chiller
cooling system optionally available)
“CE Mark” Certified; this is a CDRH Class IV laser product
