High Powered Lasers

Sanan’s family of high-power multi-mode diode lasers provide high brightness and power with exceptional reliability for a wide variety of applications in the medical, telecom, and printing industries. With a broad range of wavelengths available in-house, Sanan offers a unique opportunity for fast and cost-effective designs and manufacturing for high power laser applications while maintaining the same high standards for quality and reliability.

Sanan will optimize the design of its laser chips to meet customers’ optical and electrical performance specifications.

Sanan’s laser design is based on proprietary multi-quantum well laser partially coherent broad-area emitters with fairly uniform emission over the emitting aperture. In-house MOCVD growth and processing allows full design optimization for the customer’s specifications including filling factors, emitter size, etc.
