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).
