Cascades™ Horizontal Stacked Arrays
Combining nLIGHT’s high-power Cascades™ diode laser bars with a scalable package design, the Cascades™ horizontal stacked array product series provides a unique package optimized for side-pumping applications, but also adaptable for other uses.
Available wavelengths range from 808 nm to beyond 2000 nm, and up to 12 bars can be arranged in a single package.
