FUTURE APPLICATION OF LASER

OPTICAL TWEEZER

An optical tweezer uses a focused laser beam to provide an attractive or repulsive force depending on the refractive index to physically hold and move microscopic dielectric objects.

It is capable of manipulating nanometer and micrometer-sized dielectric particles by exerting extremely small forces . The laser contains a very strong electric field gradient. It turns out that dielectric particles are attracted along the gradient to the region of strongest electric field, which is the center of the beam.

They are often used to manipulate and study single molecules by interacting with a bead that has been attached to that molecule. DNA and the proteins and enzymes that interact with it are commonly studied in this way.

MILITARY APPLICATION

SCI-FI TURNED REALITY

The US Air Force airborne laser, (ABL), designated YAL-1A, is a high-energy laser weapon system for the destruction of tactical theatre ballistic missiles, which is carried on a modified Boeing 747-400F freighter aircraft

AircraftBoeing 747-400FEngines4 x GE engines, type CF6-80C2BSFLaser TypeMegawatt Chemical Oxygen Iodine Laser (COIL)Laser Wavelength1.315 microns

The laser weapon uses three laser beam systems: the powerful killing laser beam or primary beam, a set of illuminating laser beams and a beacon laser.

The primary laser beam is generated by a megawatt chemical oxygen iodine laser (COIL) located at the rear of the fuselage, which lases at 1.315 micron wavelength.

A low-power, multiple beam, track illuminating laser (TILL), is used to determine the target's range and provides initial information on the atmosphere through which the beam is being transmitted.

The beacon illuminating laser (BILL) . The kilowatt class BILL reflects light from the target to provide data on the rapidly changing characteristics of the atmosphere along the path of the laser beam.

HUMAN HEALTH

Treatment with low-level laser helps to promote the release of endorphins in the body.

Omega uses a low powered (soft) laser to treat nicotine addiction. The laser is no more powerful than a 60-watt light bulb.

Energy points related to addiction are identified and treated with a combination of a helium neon laser and electrobiostimulation.

The entire procedure is external, non-invasive, and non-thermal.

Laser Therapy is painless. During the laser treatment energy points on your hands, face, and ears are treated.

The low-level laser acts as a tool to assist the client through the initial physical withdrawals from nicotine
