Diode laser modules provide extremely compact and reliable sources of laser light with minimal heat generation and maximum resistance to mechanical shock and vibration. Most operate in a single longitudinal mode and provide linearly polarized output.

STANDARD DIODE LASER SYSTEMS provide excellent output power and pointing stability from an ultra-compact laser head. This is achieved through state-of-the art thermal management and hermetic sealing, which improves performance and reliability in harsh environments.

CUSTOM DIODE LASER SYSTEMS for OEM applications can be configured for direct analog and/or digital modulation, eliminating the cost, complexity and alignment challenges associated with external modulators. We also specialize in custom-tailored beam profiles that deliver the precise spot you need at the point of work, dramatically reducing system complexity and cost—and significantly improving system performance.
