ABSTRACT:
A fiber laser 26 including a rare-earth doped fiber laser cavity 32 delimited by a pair of reflective elements 28,30, such as Bragg gratings, is tuned by compressing the cavity 32 and the gratings 28,30. Because an optical fiber is a much stronger under compression than in tension, the laser 26 is tunable over a much broader range than conventional tension/stretching techniques.
