Blue Sky Research is a world leading expert in precision fiber coupling of laser diodes including; red, green, blue, violet, and IR laser diodes (405nm to 980nm). The FiberTec laser modules feature one fiber-coupled, high performance laser diode with integrated electronics that provide LD drive, temperature stability, protection and other functions. For example, RoHS compliant electronics provides ESD protection, laser driving current monitor, shutdown function, laser modulation and overdrive protection.
Key Features of FiberTecTM Fiber Coupled Lasers
Fiber Coupled laser products use a direct laser coupling system which efficiently couples a lasers power into an optical fiber and ensures the system never needs alignment through the products lifetime. Enhanced performance and reliability testing ensures exceptional product performance. System level products integrate temperature controlled lasers with individual driving, control and stability electronics.
The unique properties of optical fibers allow a reduction in optical systems complexity and enable lower system cost. System performance can be optimised while using cost effective fiber for light relay and beam shaping. A single mode fiber maintains near perfect Gaussian beams without introducing aberrations. In addition, optical fibers maintain beam pointing and steering tolerances throughout temperature variations better than all traditional optics, enabling a robust and stable system performance over wide operation conditions.
