Introduction[edit | edit source]
LASER means Light Amplification from Stimulated Emission of Radiation.Laser is created by specific process within the laser device to cause the controlled emission of radiation in form of light.Lasers were first invented by physicist Gordon Gould in 1958 and first working model was built in 1960.They have been used in Europe and America for more than forty years and have been used in fields of dermatology,surgery. opthalmology and physical medicine and rehablitation. Laser is used by physiotherapists for releif of pain,to accelerate healing and decrease inflammation.[edit | edit source]
Production of Laser[edit | edit source]
Laser device is made up of an optical cavity or chamber that contains active medium for which laser is named.The chamber has mirrors on either end that are perfectly parallel to each other within a single wavelength of light.One of the mirror is partially open.Electricity or energy is added to the medium which excites it.The active mediums atoms are reflected back and forth across the mirrors within the chambers.this causes more excitation of atoms within the medium.Laser light is then emitted through the partially reflective end of mirror.The light production occurs in the following steps:[edit | edit source]
1.Electron is pumped to a higher energy level.[edit | edit source]
2.Pumping level is unstable so the electron quickly jumps to a slightly lower energy level.[edit | edit source]
3.Electron relaxes to a lower energy state and releases a photon.[edit | edit source]
4.Light and an electron in an excited energy level produces two photons of same wavelength and phase.[edit | edit source]
5.Mirror reflects the photons or laser light is emitted.[edit | edit source]
Properties of Laser[edit | edit source]
Due to specific nature of how laser is produced it also has specific properties;[edit | edit source]
1.Monochromatic - Monochromaticity refers to the colour or wavelength of the light.since laser is produced from a single active medium laser light is one colour, one wavelength.[edit | edit source]
2.Coherent and Parallel- Due to common wavelengh of laser light ,the phase of each wavelength is also common.Light travels in sine waves in phase relationship with one another with peak and valleys precisely coinciding and reinforcing each other so laser light travels as parallel beam spreading very little.[edit | edit source]
How does Laser Work[edit | edit source]
When the light source is placed against the skin,the photons penetrates several centimeters and gets absorbed by the mitochondria. The energy fuels many positive physiological responses resulting in restoration of normal cell morphology and function but at enhanced rate.Targeted in haemoglobin and cytochrome oxidase,the high power diode laser could help in respiration and then in result have a good performance therapy.
