Cold laser therapy may seem like a treatment that one would read about in a science fiction novel. Just in the past decade‚ however‚ it has become a recognized and often times preferred treatment for osteoarthritis knee pain sufferers who want to avoid invasive procedures. Cold lasers are handheld‚ non-surgical devices that are used in a clinical setting. They work by emitting specific wavelengths of light thereby stimulating activity in the tissue on a cellular level.

Laser technology has gotten a pretty bad rap from its portrayal in movies. Usually‚ it is a device used to injure someone or as a weapon of mass destruction meted out on an unsuspecting individual. The truth is that lasers surround you every day. They are used in a variety of applications ranging from medical to scientific. Technological advancements in the science and function of lasers has even crossed over into the dental industry. Laser teeth whitening procedures have become a typical way to

input hardware has been a major field of exploitation by developers. Virtual laser keyboard has been a major breakthrough in this field. The keyboard which is non-physical has brought a new dimension in the field of data entry where the mechanical keyboards can be replaced by a light beam projected on a flat surface. It replaces the physical key board which occupy space on the devices. This paper focuses on the virtual laser keyboard as a revolutionary invention in multimedia and data entry industries

532 nm laser was generated using Q-switched Nd:YAG laser of pulse width 7 ns and 10 Hz repetition rate was used for damage studies. The NS laser was focused by a convex lens of 100 mm focal length. The sample was kept 1 cm above to the focus of the laser for the measurements‚ where the spot size is 220 µm and the energy of the laser was measured using suitable energy power meter. The good transmission behavior and lower reflectance of the crystal proves that the laser induced damage on

The eight step is to shine the three different lasers through each clear glass cup and determine the refractive angles with the three different lasers. The ninth and last step is to record (on a piece of paper) the three different angles of refraction with its corresponding laser wavelengths on a data
