Objectives
2) To implement a BLISS prototype for a SPAT system A discretely-sweeping BLISS prototype in the 1.0-μm wavelength window for a SPAT system will be implemented and its performance thoroughly characterized in a number of respects, including wavelength-sweeping range, pulse energy and pulse width, repetition rate, and synchronization. This stage of the research provides a well-characterized 1.0-μm BLISS prototype for SPAT application and a development platform for the last phase of the research; 3) To explore application of the synchronized 1.0-μm and 1.55-μm BLISS in a hyperspectral SRS system Leveraging the previous two phases, we will explore application of the synchronized 1.0-μm and 1.55-μm BLISS in a hyperspectral SRS system. In particular, one BLISS oscillating at 1.55 μm (or 1.0 μm) will be externally driven by another stable source (another BLISS) oscillating at 1.0 μm (or 1.55 μm), which can be used as the Stokes and pump wavelengths, respectively in a hyperspectral SRS imaging system. Thorough study of this aspect of BLISS performance will lay the foundation for its use in capturing hyperspectral SRS images towards the end of the research.
