    Abstract: The present invention relates to methods for laser surgery and growth factor stimulation for ultra-precision surgery with healing. The method is achieved by cutting biological tissue using an ultrafast laser, which produces laser pulses less than 10 picosecond in duration, to induce a cold ablation process in order to avoid the formation of carbonaceous or other materials that cannot be removed efficiently or completely from the wounded area through natural healing mechanisms. By use of femtosecond lasers, a negligible amount of debris is generated and an outer layer of intact but non viable cells are created principally through shock wave induce damage and ionizing radiation effects induced by multiphoton absorption of ultrashort laser pulses. The normal healing process is blocked by this outer layer of cells as all cell contacts are still intact. Therefore the healing process must be stimulated. The healing may be triggered or accelerated, or both, by application of growth factor molecules and/or signal proteins to the effectively undamaged cells causing the damaged cells to be replaced and the wound to close. The combination of very precise laser cutting used in combination with growth factors is the key to this unique tool.

    Abstract: Method for high power optical amplification of ultra-short pulses in IR wavelength range (0.7- 20 µm). The method is based on the optical parametric chirp pulse amplification (OPCPA) technique where a pico-second or nanosecond mode locked laser system synchronized to a signal laser oscillator is used as a pump source or alternatively the pump pulse is created from the signal pulse by using certain types of optical nonlinear processes described later in the document. This significantly increases stability, extraction efficiency and bandwidth of the amplified signal pulse.á Further, we disclose several practical methods of shaping the temporal and spatial profiles of the signal and pump pulses for optimization of the OPCPA interaction.

    Abstract: A multi-mode ring scanner (MMRS) has a ring unit for wearing on a finger. The MMRS optionally has a wrist unit coupled to the ring unit, such as via a cable. The MMRS optionally communicates wirelessly with a computing device. The ring unit has one or more scanners (such as an optical scanner or an RFID tag reader). The ring unit optionally has two paddle switches for activation by inward pressure from fingers adjacent to the finger. The two switches enable specifying operation of the MMRS in a plurality of modes and/or to communicate a plurality of information codes to the computing device. The computing device is optionally enabled to assign a function to each combination of activation of the two switches. A scanning system including the MMRS optionally provides feedback to a user based on feedback from a host processor.
