…fabrication of different FBG types
without operator handling. The optical fiber is mounted in a
modular fixture and is positioned on a linear stage that allows
FBGs to be written along the fiber in a precise position in an
automated fashion. Moreover, the total system cost is…

…ps. A fraction of these 50- to 200-ps pulses is injected into an amplification stage, where the pulses are amplified to the millijoule level. At
this point, the pulses are ejected from the amplification stage, usually with an EOM, and become recompressed close to the original pulse duration…

…relevant will appreciate the help from a
beam diagnostic system because the conversion efficiency of a non-linear crystal in an amplifier stage depends
strongly on the uniformity and excitation intensity of the pumping beam from the pump laser. One of the most
important considerations…

…femtosecond, regime. These industrial ultrafast lasers typically utilize a mode-locked, diode-pumped,
solid-state laser as a seed for one or more stages of subsequent amplification.
There are several different variations on the way laser ablation is used to cut glass, but in all of them,…
