The LLM01 (Laser Light Module 01) is an adaptive target acquisition module made by Rheinmetall Soldier Electronics GmbH in Stockach, Germany. It is designed to be mounted with a metal integral quick release clamping adapter on the left side of the carry handle adapter of Heckler & Koch G36 assault rifles .
Optical molasses schematic. Optical molasses is a laser cooling technique that can cool neutral atoms to as low as a few microkelvin, depending on the atomic species. An optical molasses consists of 3 pairs of counter-propagating orthogonally polarized laser beams intersecting in the region where the atoms are present.
Interference of atom matter waves was first observed by Esterman and Stern in 1930, when a Na beam was diffracted off a surface of NaCl. [7] The short de Broglie wavelength of atoms prevented progress for many years until two technological breakthroughs revived interest: microlithography allowing precise small devices and laser cooling allowing atoms to be slowed, increasing their de Broglie ...
In the rest frame of the atoms with velocity, , in the atomic beam, the frequency of the laser beam is shifted by . In the presence of a magnetic field B {\displaystyle B} , the atomic transition is Zeeman shifted by an amount μ ′ B / ℏ {\displaystyle \mu 'B/\hbar } (where μ ′ {\displaystyle \mu '} is the magnetic moment of the transition).
A photograph showing two Fulton MX-991/U Flashlights, next to an unofficial reproduction and a standard angle-head flashlight. The MX-991/U Flashlight (aka GI Flashlight, Army flashlight, or Moonbeam [1]) from the TL-122 military flashlight series of 1937-1944 and is a development of the MX-99/U flashlight issued in 1963 [clarification needed].
They produce a well controlled continuous beam spanning up to 100 ms, whereas their predecessor produced only short pulses of atoms. However, this does not constitute a continuous atom laser since the replenishing of the depleted BEC lasts approximately 100 times longer than the duration of the emission itself (i.e. the duty cycle is 1/100).
Ukraine has developed a laser weapon capable of shooting down targets from more than a mile away, the country’s drone force commander has claimed. Speaking at a defense summit in Kyiv this week ...
A laser with a relatively high intensity is sent through the atomic vapor, known as the pump beam. Another counter-propagating weak beam is also sent through the atoms at the same frequency, known as the probe beam. The absorption of the probe beam is recorded on a photodiode for various frequencies of the beams.
