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： Aspects of the disclosure relate generally to a circuit for sustaining an radio frequency (RF) modulated optical signal. The circuit may comprise a self injection locking component having a fiber optic delay line over which a portion of the optical signal propagates. The circuit may also comprise a self phase locked loop component having at least two fiber optic cables having different lengths and over which another portion of the optical signal propagates and a phase detector coupled to the at least two fiber optic cables and configured to determine a phase difference between the signals propagating over one of the respective fiber optic cables. The circuit may further comprise a voltage controlled oscillator configured to generate a stable oscillating signal in response to signals generated by each of the self injection locking and self phase locked loop components, the stable oscillating signal being configured to sustain the optical signal.

摘要： This invention provides a solution for operating a mode-locking and cavity dumping laser apparatus using single electro-optical switch or modulator (2), such as a Pockels cell, without the need of multiplexing between two sources of voltage. The complex waveform of electrical signal, which controls the Pockels Cell (2) is achieved by employing the phenomena, called LC circuit ringing, where LC circuit is formed from an inductive element and a capacitor, where the Pockels Cell works as a capacitor itself. The ringing frequency should be calculated such that the period of oscillations is preferably two times longer than the round-trip time of a light pulse inside the optical cavity. As a result, optical losses are created inside the cavity with a period, which coincides with the travel of a light pulse, thus the pulse build-up is consistent and stable.

The tunable laser cavity includes an optical resonator (16), the optical resonator (16) having a configuration, optical properties and dimensions such that a first round-trip time of the laser light (12) having the first wavelength in the optical resonator differs from a second round-trip time of the laser light (12) having the second wavelength in the optical resonator (16); a gain medium (18) inserted in the optical resonator (16), the gain medium (18) being responsive to the pump light for converting the pump light to the laser light (12); a pump light input port (20) optically coupled to the gain medium (18) for receiving the pump light and conveying the pump light to the gain medium (18); an optical intensity modulator (22) inserted in the optical resonator (16) for absorbing a portion of the laser light (12) as the laser light (12) propagates back and forth in the optical resonator (16), the optical intensity modulator (22) having a light absorption coefficient that is modulated with a modulation period, the modulation period being selectively adjustable between a first modulation period value and a second modulation period value, the first and second round-trip times being substantially equal to a respective integer multiple of respectively the first and second modulation period values; and an output port (24) for releasing the laser light from the optical resonator (16).

摘要： This application describes coupled and non-coupled opto-electronic oscillators with enhanced performance. Coupled OEOs implement a dispersion compensation mechanism to reduce dispersion-induced optical loss, a polarization control mechanism to reduce polarization-dependent optical loss, or a combination of the dispersion compensation mechanism and the polarization control mechanism to enhance the oscillator performance.

摘要： A modulated saturable absorber controlled laser. The laser includes an active medium (12); a saturable absorber material (18) operationally coupled to the medium to serve as a passive Q switch; and an energy source (20) disposed external to the medium for apply energy to the absorber. In particular embodiments, the energy source is a diode laser and focusing optics are included between the diode laser and the absorber. Modulation of the gain at the photon round trip time in the laser resonator causes a mode-locked laser output. A dichroic beamsplitter (24) is included in this embodiment for directing energy to the absorber. In an alternative embodiment, the diode laser is a quasi-monolithic diode laser assembly ring (27).
