... No. 19057), both of which can be tracked to within 30 nm in the plane at 1/60 sec intervals using digital video microscopy [5]. The two sizes can be distinguished reliably, and typical trajectories appear in Fig. 2. Colloidal silica spheres are roughly twice as dense as water and settle into a monol ...

Ultrashort laser pulse generation
... Ultrashort laser pulse generation1 Concepts for mode locking We have concluded in Chapter VIII-1 that rendering axial cavity modes to oscillate at equidistant frequencies in a phase locked manner results in the emergence of a single pulse that circulates in the laser cavity. Whenever this pulse arri ...

... section”1. In optical fiber, this typically is larger than the fiber core, since a portion of the light propagates through the cladding. MFD traditionally has been determined using a Gaussian approximation of the intensity distribution with the MFD defined as the width of the curve at the 1/e2 power ...

... They lose some of their energy into heat and results in an attenuated output signal. The bouncing rays and the lowest order mode, traveling down the center axis, are all traversing paths of different lengths from input to output. Consequently, they do not all reach the right end of the fiber optic c ...
