Laser-tissue interaction involves the absorption of laser energy by biological tissues, leading to effects such as cutting, coagulation, or ablation, depending on the laser parameters and tissue properties. Understanding these interactions is crucial for optimizing medical procedures like laser surgery and phototherapy, ensuring precision and minimizing damage to surrounding tissues.

Biological tissues are groups of cells that work together to perform specific functions, forming the structural and functional units of organs in multicellular organisms. They are categorized into four primary types: epithelial, connective, muscle, and nervous tissues, each with distinct roles and characteristics.

Cutting refers to the process of removing material from a larger piece to achieve a desired shape or size, utilizing tools or techniques that separate the material along defined lines. It is an essential technique in various fields such as manufacturing, construction, and crafts, and involves understanding material properties and tool selection to achieve precision and efficiency.

cutting

Coagulation is a complex process by which blood forms clots to prevent excessive bleeding when a blood vessel is injured. It involves a cascade of events that activate specific proteins and platelets to form a stable clot, crucial for maintaining hemostasis and wound healing.

coagulation

Ablation is the process of removing material from a surface through erosion, melting, or vaporization, often employed in medical procedures, manufacturing, and scientific research. It is crucial in contexts such as laser surgery, aerospace engineering, and climate science, where precise material removal is essential for functionality and safety.

laser parameters

Tissue properties refer to the intrinsic characteristics of biological tissues that determine their behavior and function under various physiological and mechanical conditions. These properties include aspects like elasticity, viscosity, density, and permeability, which are crucial for understanding tissue function, disease progression, and the development of medical treatments and devices.

Laser surgery is a medical procedure that uses focused light beams to perform precise surgical interventions, minimizing damage to surrounding tissues and often resulting in quicker recovery times. It is widely used in various fields such as ophthalmology, dermatology, and oncology, offering a less invasive alternative to traditional surgery.

Phototherapy is a medical treatment that uses specific wavelengths of light to treat various health conditions, most commonly skin disorders like psoriasis and eczema. It works by exposing the skin to ultraviolet light, which can reduce inflammation, slow down the growth of affected skin cells, and alleviate symptoms.
