Our 1-cm wide, MOCVD grown GaAs or InP arrays consist of multiple transverse mode emitters, which provide low beam divergence and narrow spectral bandwidth. CascadesTM horizontal stacked arrays are available in a wide range of wavelengths between 790 nm to 980 nm, and 1400 to 1600 nm. The design of these devices allows multiple packages to be placed side by side. Standard packaging footprint allows these stacks to easily integrate into your product. • Solid-state laser pumping • Materials processing • Medical therapeutics • Highest power • High reliability • Low bar smile • High polarization purity CASCADESTM HORIZONTAL STACKED ARRAYS Applications Features Package dimensions CascadesTM Horizontal Stacked Arrays, 6 bar
