Which laser beam can travel through clear tissues without heating them?

CO2 laser
Argon
Nd:YAG
Diode laser

The correct answer is: Argon

The Argon laser is known for its ability to selectively target specific tissues without significantly heating surrounding clear tissues. This characteristic comes from its wavelength, which is in the visible spectrum and allows for precise interaction with pigmented or vascular tissues, while minimizing thermal damage to adjacent structures. The Argon laser is often used in various surgical procedures, such as ophthalmic surgeries, because it can effectively photocoagulate tissues or seal blood vessels at the selected site without affecting the clear, surrounding tissues. This selectivity is key in maintaining the integrity of adjacent healthy tissues, allowing for safer and more effective surgical outcomes.
