And since you’re here, you’re probably looking for that info too. The ruby laser requires high power pumping source. This is the oldest type of laser used for hair removal purposes. Difference between SISO and MIMO This is achieved by high energy flash -Two energy levels in active amplifying medium are required. Ruby laser pulse lengths are generally a millisecond in length. Reference: This article is referred from my authored book “optics and lasers” having ISBN 81-272-2948-2. They can also be used as decoration piece and artistic display. The laser output is not continuous but occurs in the form of pulses of microsecond duration. ➨Efficiency of this laser type is comparatively lower. The Cons of Laser Tattoo Removal May Cause Skin Irritation. light excitation. The ruby laser uses a ruby crystal to emit light pulses at various wavelengths to target brown spots and other skin pigmentations. Following are the drawbacks or disadvantages of Laser: ➨It is expensive and hence more expenditure to the patients requiring laser based treatments. But it is in the form of pulse in the ruby laser. CO2 laser technology is one of the earliest lasers to be developed and is one that is still widely used today. 3. Efficiency of helium-neon laser is more than ruby laser. The drawback of the ruby laser was its pulsed and uneven output. Because a powerful beam of light passes over the tattooed skin several times, the affected area is left red and sensitive to the touch. lattice, which provides metastable energy states in solid state medium. The use of the laser in general surgery is slightly over ten years.
