Abstract

Most recently, the second (1100-1350 nm), third (1600-1870) and fourth (2100-2350 nm) NIR windows have received increased attention for use in linear and nonlinear imaging and spectroscopy. Due to minimal scattering and absorption at these windows, there is a reduction in blurring and image quality is enhanced. SWIR wavelengths can penetrate deeper than when using conventional methods and are being utilized for medical applications including brain imaging, identifying bone micro-fractures and delineating breast cancer margins. The supercontinuum laser can provide a powerful broadband light source that will increase SWIR applications. Recent advances will be discussed.
