    Abstract: The present disclosure relates to a methods and systems for high speed laser surgery. In some implementations, the combination of mid-infrared (mid-IR) laser radiation with micro-scanning technology allows for large tissue ablation rates with minimal thermally affected zones, where micro-scanning distributes the heat generated by laser surgery over a large tissue area. Micro-scanning technology is compatible with hollow core fiber technology which can be implemented to deliver near diffraction limited mid-IR laser beams into the vicinity of the target area. Micro-scanning technology is compatible with hand tools for direct replacement of mechanical surgical tools such as scalpels as well as robotic surgery. Micro-scanning technology is also compatible with endoscopic beam delivery and can be combined with endoscopic tissue analysis. Tissue analysis can be performed with optical imaging technology as well as other analytical tools such as mass spectrometers.

    Abstract: Coherent and compact supercontinuum light sources for the mid IR spectral regime are disclosed and exemplary applications thereof. The supercontinuum generation is based on the use of highly nonlinear fibers or waveguides. In at least one embodiment the coherence of the supercontinuum sources is increased using low noise mode locked short pulse sources. Compact supercontinuum light sources can be constructed with the use of passively mode locked fiber or diode lasers. Wavelength tunable sources can be constructed using appropriate optical filters or frequency conversion sections. Highly coherent supercontinuum sources further facilitate coherent detection schemes and can improve the signal/noise ratio in lock in detection schemes.

    Abstract: Examples of methods and systems for laser processing of materials are disclosed. Methods and systems for singulation of a wafer comprising a coated substrate can utilize a laser outputting light that has a wavelength that is transparent to the wafer substrate but which may not be transparent to the coating layer(s). Using techniques for managing fluence and focal condition of the laser beam, the coating layer(s) and the substrate material can be processed through ablation and internal modification, respectively. The internal modification can result in die separation.
