Uses Of Ruby Laser

The ruby rod is the lasing medium and the flash tube pumps it.

Uses of ruby laser.

The light excites atoms in the ruby. These chromium ions give the crystal a pink or red color. In a ruby laser optical pumping technique is used to supply energy to the laser medium. Leon goldman who is recognized as a pioneer in laser medicine used the ruby laser for treatments such as tattoo removal scar treatments and to induce healing.

Ruby is a crystal of aluminium oxide in which some of the aluminium ions are replaced by chromium ions. It is rarely used in industry due to its low repetition rates and low. The first working laser was a ruby laser made by theodore h. The ruby laser was the first laser used to optically pump tunable dye lasers and is particularly well suited to excite laser dyes emitting in the near infrared.

Ruby lasers were used mainly in research. A ruby laser is a three level solid state laser that uses a ruby crystal as its gain medium. Maiman in 1960 3. Optical pumping is a technique in which light is used as energy source to raise electrons from lower energy level to the higher energy level.

Ruby laser principle structure a ruby laser is a solid state laser that uses a synthetic ruby crystal as its gain medium. Ruby lasers are used for holography industrial cutting and welding. Ruby lasers are rarely used in industry mainly due to low efficiency and low repetition rates. The flash tube fires and injects light into the ruby rod.

It has wavelength of 6943 angstroms. Ted maiman at hughes research laboratories on may 16 1960. The laser in its non lasing state 2. Ruby laser has very high output power of the order of 10 4 10 6 watts.

Ruby laser has following uses or advantages or applications. It is effective at eliminating or reducing the appearance of brown spots and age spots that appear on the skin as a result of sun exposure genetics and hormones. A ruby laser consists of a flash tube like you would have on a camera a ruby rod and two mirrors one half silvered. Rangefinding is one of the first applications of the ruby laser.

The ruby laser was the first laser to be used in medicine.
