Such Rods are 2 to 30 cm in length and 0.5 to 2 cm in diameter. ➨Beam diameter of ruby laser is comparatively less than CO2 laser type. • Since the ruby is in solid form therefore there is … Ruby laser has very high output power of the order of 10 4 – 10 6 watts. Before the output power attains steady-state value through damped relaxation oscillations. These energetic pulses of very short duration are spikes and the phenomena of generating these pulses are spiking. Frequent cooling is required as a lot of heat energy is produced during its operation. If the laser is pumped by a flashlamp, pulse widths in the range of 100 to 1000 microseconds are typical. with chromium (Cr). However, in 1962, by using very intensive pump, using arc lamp with high pressure Mercury vapor, a continuous wave Ruby laser was build. Difference between SC-FDMA and OFDM In other words, the ruby laser operates in pulse mode and hence called pulsed laser. Solid state lasers, such as ruby lasers, Nd: glass and Nd: YAG lasers that produce high powers are generally pulsed with widely different pulse durations and with different methods of pulsing. The Monochromaticity may be affected by the crystalline Imperfection. the active medium. The Q-switched ruby laser (QSRL) used for dermatological applications works on the principle of selective thermolysis.

The authors describe the possibilities and advantages of ruby laser treatment of large congenital nevi as an alternative to surgical excision. Following are the drawbacks or disadvantages of Ruby Laser: diation from the ruby laser becomes more intense, the fluorescent light is reflected at the boundary between the vessel and the surrounding air, and stimulates the dye further until the dye itself emits laser radia-tion. The pumping efficiencies can be increased by using cylindrical Mirrors. A large amount of energy is required to Trigger laser oscillations. Hence they are used as toys for children. This Photon Travels through the Ruby rod in a direction parallel to the axis of the rod and reflects back and forth (or to and fro) by the reflecting ends of the optical resonator until it Stimulates an excited chromium ion. The literature (from 1980 to 2002) is reviewed and a case report is presented. Long term hair removal can be achieved. The Stimulated transition of chromium Ion from metastable state E2 to the ground state E1  is known as laser transition.

The ruby laser is a pulsed laser of low repetition rate—the repetition rate being the number of pulses that are sent by a laser per 1 second. The end faces of the rod are silver so that the Surface of the one end face becomes fully reflecting. Typical ruby laser pulse lengths are of the order of a millisecond. As the terminus of laser action is the ground state, it is difficult to maintain the population inversion. These in-phase photons stimulate more chromium ions and hence the number of photons emitted increases. That is the energy level of chromium Ion takes part in the lasing action. The opposite ends of ruby rod are flat and parallel; one end is fully silvered and the other is partially silvered (i.e.) 3.
