Abstract:
An optical gain fiber for use in high power (e.g., greater than 500 W pump power) is proposed that is configured to exhibit a minimum bend radius such that the bend loss for the propagating LP 01  mode is greater than about 0.03 dB/m. It has been discovered that this bend radius criteria, which is less stringent, than that typically suggested in the art (e.g., bend loss less than about 0.03 dB/m), meets the modal stability requirements at high power operation, since the increase in operating temperature of the fiber laser or amplifier has been found to somewhat relax the bend radius requirement (which was heretofore only measured at “room temperature”, not “operating temperature”). Modal stability is defined in terms of a reduced presence of unwanted higher-order modes (such as the LP 11  mode) in the amplified output signal.

Claim (Index 12):
The fiber-based optical amplifying system as defined in  claim 8  wherein the optical gain fiber is configured as a center-coupled spiral with the first input endface at a center location of the spiral, exhibiting a minimum bend radius and the second output endface at an exterior termination of the spiral, exhibiting a maximum bend radius.
