OPTIMIZED CASCADED RAMAN FIBER-BASED LASER SOURCE FOR HIGH EFFICIENCY MID-INFRARED SPECTRAL GENERATION

Title:

OPTIMIZED CASCADED RAMAN FIBER-BASED LASER SOURCE FOR HIGH EFFICIENCY MID-INFRARED SPECTRAL GENERATION

Document Type and Number:

WIPO Patent Application WO/2010/011389

Kind Code:

A3

Abstract:

A laser structure is provided that includes a pulsed source producing a pulsed signal having a low spontaneous noise component to its spectral output and a pulse-shape that is optimally flat. Also, the laser structure includes one or more optical fiber structures receiving the pulsed signal and performing Raman amplification. The pulsed signal is used to excite in the one or more optical fiber structures possessing normal chromatic dispersion, which acts as a nonlinear system for efficient mid- infrared spectral generation.
