Abstract :
The use of long-period fibre gratings (LPGs), which provide a wavelength specific loss in a cavity, in order to change the emission wavelength of a fibre laser, is introduced. Using a moderately strong LPG, the output wavelength of an Nd3+-doped aluminosilicate fibre laser is forced to operate at 1088 nm; a wavelength relating to Nd3+ ions situated in Al + deficient sites.
