Abstract :
Summary form only given. Lasers based on high P/sub 2/O/sub 5/-doped fibers can potentially have a higher efficiency than Raman fiber lasers (RFL) based on standard Ge-doped fibers. An increase of phosphorus content in the fiber core gives rise to an increase of the Raman gain coefficient. Despite a rise of optical losses, heavily P/sub 2/O/sub 5/-doped fibers enable one to develop extremely efficient Raman lasers. A two-cascaded Raman laser based on a P/sub 2/O/sub 5/-doped fiber with the frequency shift of 1330 cm/sup -1/ per cascade and with Bragg gratings written directly in the P/sub 2/O/sub 5/-doped fiber demonstrated the highest ever achieved efficiency in RFL.
