Abstract: The present invention features a laser based system configured with a noise detection unit. The system includes a mode-locked oscillator. A noise detection unit includes at least one optical detector that monitors optical pulses generated by the mode-locked oscillator and produces an electrical signal in response to the optical pulses. The noise detection unit includes a first filter to transmit signal power over a signal bandwidth which includes the mode-locked laser repetition frequency, frep. The noise detection unit may include one or more filters to transmit power over a noise bandwidth that substantially excludes repetition frequency, frep. Non-linear signal processing equipment is utilized to generate one or more signals representative of the power in the signal bandwidth relative to the power in the noise bandwidth. The system includes a controller operable to generate a signal for controlling the laser based system based on the relative power.

Abstract: The present disclosure is directed to an in-liquid laser-based method for fabricating a solution of fine particles of amorphous solid medicinal compounds, a solution of fine particles of amorphous medicinal agents made with the method, and fine particles made with the method. By using a target solidified via a phase transition process to covert an initial crystalline structure into an amorphous solid, technical difficulties with handling a hydraulically-pressed target are overcome. The laser-based ablation process produces amorphous solid medicinal compound fine particles, which improves the bioavailability and solubility of the medicinal compound. The improvement results from a combination of: disordered crystalline structure and enlarged relative surface area by particle size reduction. The laser based method may be carried out with ultrashort pulsed laser systems, or with UV nanosecond lasers. Results obtained with an ultrashort near IR laser and a UV nanosecond laser show formation of amorphous solid curcumin fine particles.

Abstract: Disclosed is a process for electrophoretic deposition of colloidal suspensions of nanoparticles, especially from aprotic solvents, onto a variety of substrates. The process provides chemical additives that can be used to improve thin films deposited from colloidal suspensions by increasing the rate of deposition and the smoothness of the deposited film. In this process, a chemical additive is used to improve the properties of the deposited thin films. The chemical additive comprises a redox couple, an organometallic complex, a metallocene, a ferrocene, or a nickelocene. The colloidal suspension can be composed of semiconductor, metal or ceramic nanoparticles suspended in an aprotic polar solvent such as acetone, acetonitrile, or pyridine. The process also improves the properties of thin films deposited from protic solvents. The particles have at least one dimension ranging from 0.1 nanometers (nm) to 500 nm.
