Claim:
1. An endoscopic laser scalpel system, comprising: a surgical laser source providing laser light for at least one of incision, excision, and ablation of tissue in minimally invasive surgery; a laryngoscope or endoscope having a distal end to be inserted into a body cavity to deliver the laser light to a target tissue therein; and an endoscopic head mounted on the distal end of the laryngoscope or endoscope, the endoscopic head comprising: wherein the rotatable optical elements and the lenses are aligned with their centers on a common optical axis, and each of the optical elements is configured to rotate about the optical axis, wherein the rotatable optical elements are each structured to receive incident laser light at a first elevation angle with respect to the optical axis, and generate refracted or diffracted laser light at a second elevation angle which is different from the first elevation angle with respect to the optical axis, and wherein the refracted or diffracted laser light is generated with a second rotation angle around the optical axis that is dependent on a first rotation angle of the respective rotatable optical element around the optical axis.
