Radio waves are longest and gamma waves are shortest Wavelength Is the measurement between the distance of two consecutive peaks in a wave ( peak or troughs ) Short wave length High frequency High intensity High melanin absorption Long wave length Low frequency Low intensity Low melanin absorption Ruby laser 694nm Alexandrite 755nm Diode 800nm , 810nm Nd Yag 1064nm Ruby and alexandrite Short wave length High frequency High intensity Nd Yag Long wavelength Low frequency Low intensity Nanometers Nm How a Wavelength is measured Infrared Lasers are in this wavelength Radio wave have the longest wavelength in the spectrum Radio waves Infrared light ( IR ) Is invisible and thermal Infrared energy Felt as heat on the skin and can be captured in thermal imaging Longest wavelength visible light Red Shortest wavelength viable light Violet Some laser hair removal devices are in the red light and some are in the near infrared part of the electromagnetic spectrum Ultraviolet light Highly energetic with shorter wavelengths than visible light UVA rays 95% of UV radiation that reaches the earth UVA rays Penetrate the skin more deeply and are dominate tanning rays. Cause photo aging and skin cancer UVB rays Cause skin burns and effect the epidermis. Also cause cancer and photo aging UVC RAYS Rays are absorbed by the ozone layer and don't reach the earth Gamma rays Have the shortest most powerful wavelength and the most energetic form of light Gamma rays can kill living cells Used in medicine to kill cancerous cells Laser light Is coherent Monochromatic Collimated IPL Light Is polychromatic Scattered and Non collimated Construction of a laser 1. Flash lamp, pump source 2. Crystal, laser medium 3. Optical resonators , highly reflective mirror and a partially reflective mirror YAG Yttrium aluminum garnet Coherent energy Laser photons travel through space both temporally and spatially. Travel in Time and space in perfect unison in one direction. In phase or in step Monochromatic Laser light is composed of one wave length and one color weather visible or invisible Collimated Photon are parallel to each other in a diameter of the beam to produce a focused spot by using a lens Fluence The energy of the pulsed laser beam it is expressed in joules per cm2 Joule The unit of energy or work NS. Nanosecond Pulse duration or width is measured in Spot size Spot size is measured in mm. Millimeters Optical energy Is determined by the lasers power,spot size and the pulse duration or pulse width Laser lens Can be used to adjusted the intensity to be used for cutting, coagulation, or heating NG YAG LASER Is a solid state laser Laser therapies Laser hair removal Tattoo removal Teeth whitening LASIK Vascular lesions Pigmented lesions Selective photothermolysis By selection of a specific wavelength unique to one target chromophores. Heat can be delivered rapidly to the target before it can affect the surrounding tissue Melanin Chromophores Melanin for hair removal Hemoglobin chromophores Hemoglobin , vascular targeted for spider veins H2o water chromophores For resurfacing water is targeted since the body and tissue is made up of mainly water. TRT Thermal relaxation time Is the amount of time necessary for the target to lose 50% of the heat Laser penetration depth Penetration of laser depth from shallow to deepest Ruby , Alex,diode , nd yag FDA approved IPL for cosmetic use in the mid 1990s The mid 1990s the FDA approved intense pulse light for various cosmetic defects including pigmented and vascular lesions as well as hair IPL wavelength 400-1200 nm IPL IOL emits every wavelength of light 400-1200. Lasers emit only one wavelength Lasers emit only one wavelength of light RF. Radio frequency Alternating energy waveforms that produce localized non specific heat to the epidermis or dermis RF energy Is color blind enhancing safety. And is widely used in cellulite and skin tightening treatments The top 5 non- invasive cosmetic procedures 1. Neurotoxin injection 2. Dermal fillers injection 3. Chemical peels 4. Last hair removal 5. Microdermabrasion DSHS. Department of State Health Services DSHS Laser radiation program covers technicians for laser hair removal Level of laser techs 1. Apprentice in training 2. Technician 3. Senior technician 4. Professional technician Acne Is a common skin condition that affects the face and body with dense population of sebaceous follicles Acne vulgaris The most common type of acne Don't laser over active acne. Don't laser the active acne area Boils Also called a furuncle. It is a deep folliculitis infection of the hair follicle Boils Are most commonly caused by the bacterium staphylococcus aureus Cellulitis Is a bacterial infection of the skin caused by staphylococcus and streptococcus bacteria. Treat with oral antibiotics Folliculitis Is an infection or inflammation of the hair follicle anywhere on the body. The infection can be staph bacteria or fungus MRSA. Methicillin Resistant Staphylococcus Aureus MRSA A strain of staph bacteria that is resistant to antibiotics used to treat common staph infections HA-MRSA Hospital acquired spread by skin to skin contact , towels , razors CA-MRSA Community acquired spread by skin to skin contact , towels, razors Don't treat people with MRSA at all Ring worm.
