New Interplanetary laser

Interplanetary laser can reach to Mars and beyond

Till now, the accuracy of a laser distance is limited. These systems are founded on a passive way of a laser location so the signal worsens with 1/R 4 to R distance. In new research, physicists developed system which has the range one thousand times more exact. The system is founded on an active laser location where the signal worsens only to 1/R 2. The new system also has potential for achievement of sub-millimetric accuracy that gives the general improvement of productivity; such quality of a location is more than three orders better existing. This approach to a laser location can expand possibility of data acquisition to any interplanetary distances, at the expense of increase the sizes of telescopes. From Earth to Mars or Jupiter the laser location can already work at very modest sizes of a telescope, diameter in 1m at Earth and 15sm by the spaceship.

Circuit that produces the sound laser

Sound Lasers – Phasers

In March 18 the scientists from NTT Basic Research Laboratories in Japan built a laser with using a nanoscale drum. Instead of light, this laser uses sound waves. One day such device can be used in medical ultrasound imaging, high-precision measurements and other places. The laser was created, when the photons were emitted at a very narrow wavelength. All the photons travel in the same direction; this allows the photons to carry energy from one place to another place. More than 50 years the lasers, which had created the scientists, have used light waves. Only in 2010 the scientists built the laser, which was the first laser with sound. In this sound laser all the photons traveled together. In the all other types of lasers, gas or crystal bunch of electrons all are excited at the same time. By returning to the lower energy state, the electrons release a light wavelength. The principle of lasers work is following: the bunch of photons is jiggles and excites by the mechanical oscillator.

Nanoscale 3D Printed Race Car

Using a technique known as two-photon lithography, Austrian researchers have developed a high-precision 3D printer capable of producing nanometer sized objects in the shape of race cars, cathedrals, and bridges in a matter of minutes. The high-precision 3D printer at TU Vienna is purportedly orders of magnitude faster than similar devices, and opens up new areas of applications, such as in medicine.The super fast nano-printer uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam.
