摘要： An optical fiber amplifier system is described and comprises a first optical fiber having a doped core with a first gain spectral profile upon being pumped. The first optical fiber is adapted to receive an optical signal from a light source. A second optical fiber has a doped core with a second gain spectral profile upon being pumped. The second optical fiber is optically coupled to the first optical fiber. A pump light system is optically coupled to the fibers so as to store energy in the fibers for a subsequent amplification of the optical signal from the light source. An overlapping configuration is provided between the first gain spectral profile and the second gain spectral profile so as to reduce energy depletion in one of the optical fibers from amplification of spontaneous emission generated by another of the optical fibers.

摘要： A coupling technique for the side coupling of light from a light source into a waveguide is provided. A transversal groove is made into a section of the waveguide, extending into the target light guiding region. A coupling element is coupled to the light source at one of its end to receive the light beam therefrom. The opposite end of the coupling element is inserted in the groove and has at least one reflecting interface which specularly reflects the light beam for propagation into the waveguide. This technique may advantageously be used to couple light from the laser diodes of an array into one or a plurality of optical fibers.

摘要： Methods stabilize the output of a pulsed laser system using pulse shaping capabilities. In some embodiments, transient effects following a transition between a QCW regime and a pulse shaping regime are mitigated by ensuring that the average QCW optical power substantially corresponds to the average pulsed optical power outputted in a steady-state operation of the pulsed laser system in the pulse shaping regime. The QCW signal or the pulse shaping signal may be adapted for this purpose. In other embodiments, transient effects associated with non-process pulses emitted between series of consecutive process pulses are mitigated through the proper use of sequential pulse shaping.

摘要： A method for stabilizing an output of a pulsed laser system includes a directly modulated laser diode by mitigating the effect of switching transients on the temporal shape of the outputted pulses. The method includes controlling a pulse shaping signal to define, over time, processing and conditioning periods. During the processing periods, the pulse shaping signal has an amplitude profile tailored to produce the desired temporal shape of the output. Each conditioning period either immediately precedes or follows a processing period. During a given processing period, the amplitude profile of the pulse shaping signal is tailored so that the drive current of the laser diode is lower than its maximum value during the corresponding processing period, and is of the same order of magnitude as the laser threshold current of the laser diode. In this manner, the stability of the output during the corresponding processing period is improved.

摘要： High power optical pulses generating methods and laser oscillators are provided. A light generating module generates seed optical pulses having predetermined optical characteristics. A spectrum tailoring module is then used to tailor the spectral profile of the optical pulses. The spectral tailoring module includes a phase modulator which imposes a time-dependent phase variation on the optical pulses. The activation of the phase modulator is synchronized with the passage of the optical pulse therethough, thereby efficiently reducing the RF power necessary to operate the device.

摘要： A method and device are provided for generating bursts of sub-pulses, preferably in the picosecond range. Seed pulses are first generated, and then phase modulated to spread their spectral profile to several time-dependent spectral components. The phase modulated seed pulses are then spectrally filtered to remove spectral components and retain only selected ones, creating gaps in the amplitude profile of the seed pulses which therefore form bursts of sub-pulses. Various parameters such as the modulation amplitude, the modulation frequency, the spectral characteristics of the filters and the overall amplitude of the seed pulses may be controlled to provide a great versatility and adaptability.

摘要： A digital pulse shaping module provides a digital waveform such as a pulse shape, gating or a synchronizing digital signal for use with a pulsed laser oscillator. The digital pulse shaping module includes a waveform data generator that generates N-bit words having a number N of bits. A serializer is further provided to receive the N-bit words from the waveform data generator and outputs each bit individually in a series of bits corresponding to the digital waveform. The digital pulse shaping module further includes a delay module that provides a fine delay in the outputting of the bits by the serializer. This fine delay corresponds to a number of bits smaller than N, impacting on the timing of the outputted signal at the bit level. A pulse shaping generator has a plurality of digital pulse shaping modules.
