Biomedical Optics and Laser Applications

1064 nm wavelength is commonly used for laser skin resurfacing due to its deep penetration and minimal absorption by melanin, making it suitable for treating a variety of skin conditions.

Photovaporization is the primary mechanism of laser-tissue interaction in laser ablation, where the laser energy is absorbed by the tissue, causing rapid vaporization and tissue removal.

Angiography is an optical imaging technique that uses near-infrared light to visualize blood vessels by injecting a contrast agent into the bloodstream.

Laser-induced fluorescence spectroscopy relies on the emission of laser light by molecules when they return to their ground state after absorbing laser energy.

Nd:YAG laser is commonly used in laser lithotripsy due to its ability to generate high-energy pulses that can fragment kidney stones without damaging surrounding tissue.

Laser-induced tissue welding involves melting the edges of the tissue to be joined, allowing them to fuse together upon cooling.

800 nm wavelength is commonly used for laser hair removal due to its ability to target melanin in hair follicles while minimizing damage to surrounding skin.

Laser coagulation involves using lasers to heat and seal blood vessels, preventing bleeding during surgery.

Excimer lasers are commonly used in laser eye surgery due to their ability to precisely ablate corneal tissue, reshaping it to correct vision problems.

LITT involves using laser energy to heat tissue interstitially, causing cell death and tissue ablation.

Er:YAG lasers are commonly used in laser dentistry due to their ability to precisely ablate dental tissue and their minimal thermal damage to surrounding tissues.

Laser-induced tissue coagulation involves the use of lasers to heat and denature tissue proteins, causing coagulation and tissue destruction.

1064 nm wavelength is commonly used for laser prostate surgery due to its ability to penetrate tissue deeply and its minimal absorption by blood, allowing for precise tissue ablation.

Laser tattoo removal involves using lasers to break down tattoo pigments into smaller particles that can be removed by the body's immune system.

Dye lasers are commonly used in laser cancer therapy due to their ability to generate tunable wavelengths that can target specific chromophores in cancer cells.
