Abstract
一种窄脉冲光纤放大器,属于激光技术领域。该光纤放大器含有种子源激光器、种子光耦合系统、增益光纤、泵浦源激光器和泵浦耦合系统,其特征在于在种子源激光器和增益光纤之间加入对种子源激光器发出的脉冲进行选择的脉冲选择器。选择出的脉冲序列具有可任意变化的重复频率、持续时间,经过光纤放大器的高增益放大,得到高功率、窄脉宽的激光脉冲输出。本发明的优点是,充分利用了种子源激光器脉宽窄和光纤放大器宽增益谱、高增益的优点,脉冲选择器的加入使得脉冲的重复频率和持续时间可以自由地改变。本发明可以得到较低重复频率的窄脉宽脉冲序列,其单脉冲能量、峰值功率能显著提高,同时还避免了受激布里渊散射效应。
A narrow pulse fiber amplifier belongs to the field of laser technology. The fiber amplifier contains a seed source laser, a seed optical coupling system, a gain fiber, a pump source laser and a pump coupling system, and is characterized in that a pulse for selecting the pulse emitted by the seed source laser is added between the seed source laser and the gain fiber Selector. The selected pulse sequence has an arbitrarily variable repetition frequency and duration, and is amplified by a high-gain fiber amplifier to obtain a high-power, narrow-width laser pulse output. The invention has the advantages of making full use of the narrow pulse width of the seed source laser and the advantages of wide gain spectrum and high gain of the fiber amplifier, and the addition of the pulse selector enables the repetition frequency and duration of the pulse to be changed freely. The invention can obtain a narrow pulse width pulse sequence with a lower repetition frequency, its single pulse energy and peak power can be significantly improved, and the stimulated Brillouin scattering effect can be avoided at the same time.
