Abstract
The present invention discloses a high power diode-pumped laser for laser ablation of soft tissue. The present invention contemplates to operate the high power diode-pumped solid-state laser at a continuous Q-switching mode and at a big number of transverse modes. The present invention also contemplates to reduce beam divergence and beam spot size and thus to increase power density of the laser on target tissue to improve the speed of tissue ablation. The present invention further contemplates to minimize power consumption such that external water-cooling or secondary cooling loop can be eliminated. The present invention even further contemplates to implement combined mechanisms to protect intracavity optics from power damage. Finally, the present invention contemplates hospitals and surgeon offices to use the high power diode-pumped laser for soft tissue ablation with standard electrical wall-plug outlet and elimination of inconvenient external water-cooling or secondary cooling loop.
