摘要： The invention relates to a laser system with a passively Q-switched laser 1, a spectrally widening element 3, and a compression element 4. Laser systems of this kind are utilized for generating ultra-short laser pulses. Systems, mode-coupled solid-state lasers known from prior art allow for generating laser pulses in the sub-10 ps range only with complicated and alignment-sensitive free-beam arrangements. Therefore, it is the object of the present invention to create a laser system that generates pulse durations of less than 10 ps and which is simple and compact to produce at the same time. In order to achieve this object, the present invention proposes that the passively Q-switched laser 1 is provided with a longitudinally monomode output radiation which is spectrally widened by means of the spectrally widening element 3 by self-phase modulation and is temporally compressed by the compression element 4.

摘要： Master oscillator power amplifier (MOPA) apparatus includes two seed-pulse sources coupled to a single fiber amplifier including one or more stages of amplification. One of the seed-pulse sources is a single-mode source generating pulses having a duration selectively variable between about 0.1 ns and 10 ns. The other seed-pulse source is a multi-mode source generating pulses having a duration selectively variable between about 1 ns and 10 μs. Selectively operating one or the other of the seed-pulse sources provides that the apparatus can deliver pulses selectively variable in a range between about 0.1 ns and 10 μs.

摘要： A high power short optical pulse source 10 can include a master oscillator 12, preamplifier 14, and pump laser 16 provided within a first enclosure 28 at a first location. The high power short optical pulse source can further include a high power fiber amplifier 20 provided within an optical head 18, which is located at a second location, remote from the first location. The optical head 18 can have a small footprint and can be positioned at the intended target of optical pulses output from the high power short optical pulse source. The large, noisy elements of the high power short optical pulse source 10 are thereby provided away from the application site of the pulses.

摘要： System for converting relatively long pulses from rep-rate variable ultrafast optical sources to shorter, high-energy pulses suitable for sources in high-energy ultrafast lasers. Fibers with positive group velocity dispersion (GVD) and self phase modulation are advantageously employed with the optical sources. These systems take advantage of the need for higher pulse energies at lower repetition rates so that such sources can be cost effective.

摘要： Embodiments of optical fiber may include cladding features that include a material (e.g., fluorine-doped silica glass) that may produce a very low relative refractive index difference with respect to cladding material in which the cladding features are disposed. This relative refractive index difference may be characterized by (n1−n2)/n1, where n1 is the index of refraction of the cladding material in which the cladding features are included, and n2 is the index of refraction of the cladding features. In certain embodiments, the relative refractive index difference may be less than about 4.5×10−3. In various embodiments, the configuration of the cladding features including, for example, the size and spacing of the cladding features, can be selected to provide for confinement of the fundamental mode yet leakage for the second mode and higher modes, which may provide mode filtering, single mode propagation, and/or low bend loss.
摘要翻译：光纤的实施例可以包括包括材料（例如氟掺杂石英玻璃）的包层特征，其可以产生相对于其中设置包层特征的包层材料的非常低的相对折射率差。该相对折射率差可以由（n1-n2）/ n1表征，其中n1是其中包含包层特征的包层材料的折射率，n2是包层特征的折射率。在某些实施方案中，相对折射率差可以小于约4.5×10 -3。在各种实施例中，可以选择包括例如包层特征的尺寸和间隔的包层特征的配置，以提供用于第二模式和更高模式的基模模式的限制，而这可以提供模式滤波，单模传播和/或低弯曲损耗。
