Already first lasers have been stuied for their effects on biological materials.A great deal of experimental evidence is now acquired on laser use in medicine.commercial laser systems find their way in many clinics.
It is now carrwaon for laser surgical*its to fix the laser scalpel in a facility which provides the possibility of certain movements of the beam and its rotation.Fibre optics has put the laser scalpel into the surgeon's hand:flexible opQc fibres lead the beam to the radiator in the hand.The radiator contains a len system for beam focusing.
Laser radiation is efficient in hAEmonimge control due to cauterizing action of the laser beam on the blood vessels.Therefore,lasers are used for mduc*on of hematic losses,which is especially important for patients with poor blood coagulation.laser surgery became a roution procedure in the tx*tment of liver and lungs,and for elmination of moles and tumors developing on the skin tissues.Most common sources for these applications are CO2 and argon lasers.
Lasers are now finding increasing use in therapy.the He-Ne laser has produced curing effect on ophie ulcers,poorly healing wolmds,and bone fractures.Relatively rapid healing effect has been observed for or these cases after a few radiative treatmnents.
Stomatology is another field in medicine where the laser has also been found usefull.It has been proved capable of destroying selectively those tissues of the tooth affected by caries,that is,the laser can replace dental drills,in this function it has demonstrated a much higher performance and operated without pain.

it's not too difficult but it's too long!haha
