Which type of laser is considered the best for hemostasis?

The CO2 laser is widely regarded as the best choice for hemostasis during surgical procedures due to its specific characteristics and how it interacts with biological tissue. CO2 lasers emit a wavelength of approximately 10,600 nm, which is highly absorbed by water in tissues. This absorption results in effective vaporization of tissue while simultaneously providing significant hemostatic effects.

As the CO2 laser cuts through tissue, the intense heat generated closes off blood vessels, minimizing bleeding and promoting a clear surgical field. The combination of precise cutting abilities and effective hemostatic properties makes the CO2 laser particularly advantageous in procedures requiring both incision and cauterization, such as in dermatological and gynecological surgeries.

Other laser types, while useful for various applications, do not offer the same level of efficacy in hemostasis as the CO2 laser. For instance, the Nd:YAG laser is more suitable for deeper tissue penetration and can treat vascular lesions but is not as effective for hemostasis in surface tissues. The Er:YAG laser excels in ablative procedures but tends to produce more collateral thermal damage, which can lead to increased bleeding. Diode lasers, on the other hand, are versatile and can perform well but generally lack the same hemostatic efficiency
