A Mid-InfraRed FIber Laser (MIRFIL) has been developed that generates super-continuum covering the spectral range
from 0.8 to 4.5 microns with a time-averaged power as high as 10.5W. The MIRFIL is an all-fiber integrated laser with
no moving parts and no mode-locked lasers that uses commercial off-the-shelf parts and leverages the mature
telecom/fiber optics platform. The MIRFIL power can be easily scaled by changing the repetition rate and modifying
the erbium-doped fiber amplifier. Some of the applications using the super-continuum laser will be described in defense,
homeland security and healthcare. For example, the MIRFIL is being applied to a catheter-based medical diagnostic
system to detect vulnerable plaque, which is responsible for most heart attacks resulting from hardening-of-the-arteries
or atherosclerosis. More generally, the MIRFIL can be a platform for selective ablation of lipids without damaging
normal protein or smooth muscle tissue.
