| Abstract: | Getting low CO2 Laser power is the key technology in laser-assisted microvascular anastomosis. The technology which is used to get low CO2 Laser power from the general CO2 Laser is presented in this paper, lts main advantages are that Laser power on Laser scalper is modifiable, spot size is controllable and energy density on the light spot is uniform. We give the design principle and an example for practical design in this paper. |
