Laser Diodes

Array Submodules

CEO’s Laser Diode Array Submodules (ASMs) are offered for individual purchase and on over 200 standard diode heat sink designs. The ASMs are available with CEO’s Silver Bullet or Golden Bullet package technology, the latter of which utilizes expansion matched materials for high average power and long pulse applications. Featuring long life diode bars, the ASMs are available in continuous-wave (CW) and pulsed (QCW) operating modes. For pulsed output, more than 20 bars can be assembled onto a single ASM with a variety of bar-to-bar pitches from 150 µm – 1.7 mm. Custom options are available upon request.
