摘要: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device positioned along the optical axis of the resonator.

摘要: Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument for biological or chemical analyses. The pulsed laser may produce sub-100-ps optical pulses at a repetition rate commensurate with electronic data-acquisition rates. The optical pulses may excite samples in reaction chambers of the instrument, and be used to generate a reference clock for operating signal-acquisition and signal-processing electronics of the instrument.

摘要: Provided is a laser processing device capable of performing high-power laser processing while preventing reduction of life duration of a light source for excitation light. By collecting the light emitted from single emitters of a plurality of single emitter LDs onto one end face of an optical fiber cable, high-power excitation light is transmitted to a marking head through the optical fiber cable. Excitation light emitted from the other end face of the optical fiber cable is separated into first excitation light and second excitation light. The first excitation light excites a first laser medium to generate laser light. The generated laser light enters a second laser medium. The second excitation light enters the second laser medium. With this, the second laser medium is excited, and the laser light that has entered the second laser medium from the first laser medium is amplified.
