  3. Variables There are several variables that affect laser performance. Most of these are under the direct control of the clinician. • Power Setting • Distance – laser tip to skin • Angle • Hand speed • Skin Pigment

  4. How Does Laser Work?

  5. How Does Laser Work?

  6. What is a Diode? A diode is a two-terminal electronic component which conducts electric current asymmetrically or un-idirectionally; that is, it conducts current more easily in one direction than in the opposite direction. Cathode is a negatively charged metal electrode Anode is a positively charged metal electrode

  7. What is a Laser Diode? A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. The most common and practical type of laser diode is formed from a p-n junction and powered by injected electric current.

  8. What is a Laser Diode? Incoherent Light Coherent Light

  10. Laser Classifications Lasers are classified into four broad areas depending on the potential for causing biological damage. When you see a laser, it should be labeled with one of these four class designations: • Class I - These lasers cannot emit laser radiation at known hazard levels. • Class I.A. - This is a special designation that applies only to lasers that are "not intended for viewing," such as a supermarket laser scanner. The upper power limit of Class I.A. is 4.0 mW. • Class II - These are low-power visible lasers that emit above Class I levels but at a radiant power not above 1 mW. The concept is that the human aversion reaction to bright light will protect a person. • Class IIIA - These are intermediate-power lasers (cw: 1-5 mW), which are hazardous only for intrabeam viewing. Most pen-like pointing lasers are in this class. • Class IIIB - These are moderate-power lasers. • Class IV - These are high-power lasers (cw: 500 mW, pulsed: 10 J/cm2 or the diffuse reflection limit), which are hazardous to view under any condition (directly or diffusely scattered), and are a potential fire hazard and a skin hazard. Significant controls are required of Class IV laser facilities.

  11. Classification of LASER Technologies for Industrial Applications • - - - - - • Class I Grocery store scanner • Exempt from regulation • Class II Pointers • Low power – some regs – not on airplane • Class III Laser show lights • Medium power – more regs • Class IV Medical Use • High power &Highly regulated

  12. When LASER Energy impacts mammalian tissue 5 Optical phenomenon occur . Reflection Refraction Transmitted Absorbed Scattered Photo chemical - Breaks bonds Used with photosensitive chemicals Photo thermal – Boiling of cell juices Vaporization and eventually charing Converted Photo plasmolytic –

  13. this meeting between LASER beam and tissue • causes 5 Biological Results • Heating of Tissue • Denaturing of Proteins • Contraction of Collagen • Coagulation of Tissues • Vaporization of Cellular fluids

  14. Continuous / Pulsed / Super-pulse 3 common Wave form modes to help control the laser beam Vaporolysis occurs when LASER pulse time is less than thermal relaxation time

  15. Continuous Wave energy is continually released The faceplate power setting is the actual power release of the device in real time.

  16. Pulsed Wave energy is released in higher than average power with short periods of no energy. maximizes vaporization minimizes thermal accumulation,

  17. Super-pulse Wave bursts of energy at very high peaks of very short duration with a longer pause in between peaks Superpulse waveforms minimize thermal damage.

  18. FocusedvsDefocused Beam Focal point Many Laser delivery systems have a lens Defocused area Lens Denlaser Optical fiber Defocused area No Lens - just cleaved fiber DenLaser Beam defocuses at an angle of 12° as it exits the tip of fiber

  19. Aiming the Defocused Beam Defocused Beam No Lens just a cleaved fiber DenLaser Beam is a unique Uniformly Divergent Cone of Laser Energy

  20. With any Defocused Beam Zone A ~ at the tip - - delivers the power setting on unit Zone B ~ about 1 inch from the tip - - delivers - less % Zone C ~ 1 index finger length from the tip - even less % Defocused Beam A B C Power falls off as light goes away from the tip of the fiber

  21. <= at tip of fiber <= Zone A ~ Eraser <= Zone B ~ 10¢ Dime Zone C ~ 50¢ => Treatment Zone as f(x) of Distance from end of Optical Fiber

  22. Bio Stimulation of Tissue • photo-disruption • photo-chemistry • photo dynamic therapy • photo-fluorescence • photo – medication • Photo-bio-modulation • it’s similar to photosynthesis in plants

  23. Bio Stimulation of Tissue Photo – Medication of tissue . . . . results in functional changes within the cell - which increases cellular syntheses, membrane secretion, and motility changes . . . This improves - speed of wound healing - both acute and chronic, soft tissue healing, the immune system, promotes nerve regeneration, positively effects healing of Venous Ulcers, Diabetic Ulcers, Improves Osteoarthritis, Tendonitis, Neuralgia, shingles and Helps to relieve post-operative pain.
