  • Zecotek Completes Green Fiber Laser Development, Files for Patent
Aug 2007
Biophotonics technology developer Zecotek Medical Systems Inc. of Vancouver, British Columbia, announced yesterday that it has completed the creation of a fiber laser that operates in all known wavelengths of the green spectral range and has filed for a patent on the technology with the US Patent Office. Limited production will begin immediately, Zecotek said, with large-scale manufacture expected to begin in January 2008. Fiber lasers are more power-efficient, more compact, require less time to service, interface more easily with optical fiber channels, and deliver higher power with a high-quality beam than existing solid-state lasers, the company said. Applications for the green fiber laser series include replacement of existing ion gas and DPSS (diode-pumped solid-state) lasers used in both industrial and scientific applications. Zecotek said it is talking with potential customers in industries ranging from bioinstrumentation (DNA sequencing, flow cytometry, scanning laser microscopy); medicine (ophthalmology, dermatology, urology), printing and imaging; material processing (laser writing, lithography and sintering); and fundamental research (spectroscopy, fluorescent analysis).

fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
