The size and weight of typical surgical laser systems are such that the laser cannot be held in the surgeon’s hand like a scalpel. It is relatively immobile. Therefore some flexible, light weight device must be provided to transmit the radiant power from the laser to the surgical target.. elding. Submitted to: . Mr. : . Qamar. . Tanveer. Submitted by:.

The alignment and setup of wedge window assembly presents high potential for laser eye injury and uncontrolled secondary back reflection as a wedge consist of two reflective surfaces and can potentially be oriented in such a way to expose directly the back reflection upward or towards an undesired path. The users will learn how to safely mount and setup a wedge window.. Joshua Moody. F . Braunmüller. , M. . Hüther. , M. . Martyanov. , P . Muggli. , E. . Öz. Max Planck Institute. Gabor Demeter.
