    Abstract: 本发明提供了一种控制透射或反射光强度的光调制器。在透射模式中,分束器把任意偏振光分成两个偏振光束,并且使其中一束与另一束从不同单独的路径传输。复合器致使两光束在输出端复合,除非电光相位延迟器改变两束光的偏振,在这种情况下,错过输出端的光量是延迟器上电压的函数。通过改变复合器的取向得到低偏振模式散射的常断型调制器。通过被动的偏振方向旋转得到低偏振模式的常合型调制器。在反射模式中输入和输出处于调制器的同一侧的地方可以得到类似地结果。使用GRIN透镜的调制器特别适合于调制光输出或输入光缆。该装置可以做为一个可变光衰减器、光学开关、或高速调制器工作,并且对入射光的偏振态不敏感。对于相位延迟器的优选材料是一种热压陶瓷铅镧锆钛酸盐复合物。

    Abstract: The invention relates to an optical switch of the NOLM type and to a related optical sampler. The optical switch has a very high time resolution due to a dual passage of the signal to be switched and of the switching signal in the optical loop, wherein the second switching window during the second passage is adjusted so as to slightly overlap the first switching window during the first passage. The switch also has a very good noise ratio and high dynamics. The invention also relates to an optical sampler including means for replicating the signal to be sampled for transmitting the same to the high time resolution optical switch.

    Abstract: A laser system for generating and amplifying optical pulses with a tunable output wavelength in the near-infrared between approximately 0.75 and 2.5 μm comprises an optical parametric amplifier having a nonlinear crystal (4), an optical seed source (2) for supplying an optical seed pulse to the nonlinear crystal (4) and an optical pump source (3) for supplying an optical pump pulse to the nonlinear crystal (4). The optical seed source (2) is adapted for supplying a wavelength in a range between approximately 0.75 and 2.5 μm, and the optical pump source (3) is adapted for supplying a wavelength in a range between approximately 0.65 and 1 μm. The nonlinear crystal (4) is biaxial and can be a KTP crystal. A relatively efficient and robust mirror arrangement for such a system is also disclosed, as well as methods for generating and amplifying optical pulses with a tunable output wavelength.
