Ruby E Series

Robust stacks with 3 to 9 200W bars

Description Typical Performance Applications Characteristics Downloads

Based on the "Robust Head" concept, these vertical stacks have been qualified for a variety of very demanding land, air and space programs worldwide.
This device is designed for improved performance doubling the output power to 200W per bar and high temperature operation under conductive cooling conditions. Diode pumped laser designators and range finders based on SCD's high power Ruby stacks have been fielded and are operational in thousands systems.

Present devices incorporate high power, high efficiency, Al-free bars with nominal center wavelength at 808nm.

Thousands of these devices, including 8 and 9 bars have been produced and supplied since 2000. We thus offer a mature product with mastered production parameters. Hard Solders are used across the range of SCD's diode laser products.
