Why are 1µm lasers not as effective in surgical applications as 2µm lasers?

Radiation from 1µm lasers has much lower absorption than 2µm lasers and penetrates deeper into tissue, resulting in larger areas of injury and more unnecessary dead tissue. Because surgery is a very precise process, the depth of cuts need to be finely controlled in order to reduce damage to the underlying tissue. 2µm lasers offer this precision and should be considered for these surgical applications.
