Space-Time-Wavelength Mapping Based
... tweezers using a virtually imaged phased array (VIPA) [4–6]. We employ a VIPA to disperse a spectrum in the vertical dimension, while a grating diffracts it in the horizontal dimension, creating a 2D space-wavelength mapping. Through electro-optic modulation in time domain it is possible to manipula ...

Proposal for a Magneto-optical Beam Splitter for Atoms.
... calculation assumes that the change in the kinetic energy of the atom induced by the interaction is negligible (this is known as the Raman-Nath approximation). In the position representation the Raman-Nath regime can be interpreted as the limit where the transverse displacement of the atom during th ...

... as much as 3 inches between very weak signals and very strong ones. The sensor has a signal strength detector, which generates an analog signal that ranges from 0 to 4 volts and is logarithmic with received light intensity. This signal is used internally to generate calibrated distance measurements ...

Optical Damage Limits to Pulse Energy From Fibers - AS
... a quantitative analysis of the limits imposed by self-focusing and optical damage in these fibers, and we discuss the role SBS might play in power limiting. The literature contains several reports of multimegawatt power from passive picosecond fibers [1], and from nanosecond fiber amplifiers [2]–[6] ...

... at a level crossing, the avoided crossings caused by the field gðtÞ must be large enough compared to the level velocity to make the process adiabatic. Because ARP uses pulses of a finite duration there is only a limited window during which gðtÞ meets this criterion. With no interaction, J ¼ 0, all ...

Laser Vibrometer Measurements of Objects Immersed
... Vibrometry on submerged objects is fundamentally not different from vibrometry in air. In air, the object must be visible; in a fluid, the probing laser must also "see" the object and return enough light from the object to make an accurate measurement. In air, the index of refraction is close to one ...
