Abstract: In certain embodiments a method and system for laser-based material processing of a material is disclosed. In at least one preferred implementation temporally overlapping pulse series are generated with separate pulsed laser sources, for example nanosecond (NS) and ultrashort pulse (USP) sources (NS-USP). Pulses are delivered to the material as a series of spatially and temporally overlapping pulse pairs. The material can, but need not, be a transparent material. In some applications of transparent material processing, it was found the combination of pulses both substantially more material modification and high machining quality than obtainable with either individual pulse series taken alone. Other micromachining methods and arrangement are disclosed for formation of fine features on or within a substrate. Such methods and arrangements may generally be applied with a NS-USP combination, or with other sources.

Abstract: Examples of robust self-starting passively mode locked fiber oscillators are described. In certain implementations, the oscillators are configured as Fabry-Perot cavities containing an optical loop mirror on one cavity end and a bulk mirror or saturable absorber on the other end. The loop mirror can be further configured with an adjustable line phase delay to optimize modelocking. All intra-cavity fiber(s) can be polarization maintaining. Dispersion compensation components such as, e.g., dispersion compensation fibers, bulk diffraction gratings or fiber Bragg gratings may be included. The oscillators may include a bandpass filter to obtain high pulse energies when operating in the similariton regime. The oscillator output can be amplified and used whenever high power short pulses are required. For example the oscillators can be configured as frequency comb sources or supercontinuum sources. In conjunction with repetition rate modulation, applications include dual scanning delay lines and trace gas detection.

Abstract: The present disclosure is directed to methods of preparing stable suspensions of precious metal nanoparticles and methods for attaching bio-molecules to the nanoparticles. The formation of nanoparticles can be accomplished by either chemical synthesis or pulsed laser ablation in a liquid. The present disclosure reveals the importance of controlling the conductivity of the dispersion medium during pulsed laser ablation in a liquid to control the particle size of the nanoparticles. The present disclosure also reveals the importance of adjusting and maintaining the conductivity in a range of 25 μS/cm or less during storage of the nanoparticles and just prior to performing bioconjugation reactions. The control of conductivity is an important process for maintaining the nanoparticles as a stable non-aggregated colloidal suspension in a dispersion medium.

Abstract: Compact optical frequency sources are described. The comb source may include an intra-cavity optical element having a multi-material integrated structure with an electrically controllable active region. The active region may comprise a thin film. By way of example, the thin film and an insulating dielectric material disposed between two electrodes can provide for rapid loss modulation. In some embodiments the thin film may comprise graphene. In various embodiments of a frequency comb laser, rapid modulation of the CEO frequency can be implemented via electric modulation of the transmission or reflection loss of an additional optical element, which can be the saturable absorber itself. In another embodiment, the thin film can also be used as a saturable absorber in order to facilitate passive modelocking. In some implementations the optical element may be formed on a cleaved or polished end of an optical fiber.

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: In at least one embodiment time separated pulse pairs are generated, followed by amplification to increase the available peak and/or average power. The pulses are characterized by a time separation that exceeds the input pulse width and with distinct polarization states. The time and polarization discrimination allows easy extraction of the pulses after amplification. In some embodiments polarization maintaining (PM) fibers and/or amplifiers are utilized which provides a compact arrangement. At least one implementation provides for seeding of a solid state amplifier or large core fiber amplifier with time delayed, polarization split pulses, with capability for recombining the time separated pulses at an amplifier output. In various implementations suitable combinations of bulk optics and fibers may be utilized. In some implementations wavelength converted pulse trains are generated. A method and system of the present invention can be used in time domain applications utilizing multiple beam paths, for example spectroscopy.
