Laser Diodes in the 1300nm to 1700nm Wavelength Range achieve Higher Power.
News Release from:
21 June 2011
SemiNex makes laser diodes in the 1300nm to 1700nm wavelength range with the chips packaged in bare bars, chip-on-submount, single-emitter and multi-chip fibre-coupled modules and hermetically sealed TO-can.
A proprietary material structure is used with a non-conventional doping profile, precise growth of Indium Phosphide and a unique application of quantum physics to result in superior thermal efficiency, electrical efficiency and very short coherence length light.
The combination of superior electrical and thermal efficiency allows the lasers to achieve a power which exceeds current industry performance without compromising on lifetime.
Standard wavelengths include 1470nm, 1532nm and 1550nm with CW output optical power from 3 watts to 20 watts. The multimode diodes have small typical apertures of 95µm with the fibre-coupled products typically having a 105µm core fibre with 0.22NA.
The long wavelength of 1470nm close to the absorption peak of water and high power make them well suited for most medical applications purposes which include: wrinkle removal, acne reduction, soft tissue ablation. The 1532nm and 1550nm laser applications are: laser designators, range finders and LIDAR.
One package consists of pairing the high performance laser diodes with an effective low cost package designed for high volume capability with optical lensing and integrated cooling for dissipation of heat resulting in the most powerful CW output from single emitter lasers ready for integration into your system.
The unique approach towards laser manufacturing yields high performance and product reliability at competitive costs with experience in customer focus and applications with capabilities of custom product design.
