Laser Diode Construction: Golden Bullet vs. Silver Bullet

silver&goldenNorthrop Grumman – Cutting Edge Optronics (CEO) manufactures laser diode arrays based on two main types of technology, hard solder (CEO Golden Bullets) and soft solder (CEO Silver Bullets). Golden Bullets are state-of-the-art and are built using gold-tin solder and heat sinks that have the same CTE (coefficient of thermal expansion) as the laser diode bar. As a result, arrays built from Golden Bullets are extremely resistant to solder creep and other failure modes that result from thermal expansion and contraction in the array.
