Laser emission systems for surgical and other therapeutic uses are herein disclosed. In the preferred embodiments, different laser control systems are disclosed and disposable tips and fiber with a unique connection structure are utilized. By being disposable, the tips are manufactured to minimize material loss while also providing the confidence patients desire for their health which comes from knowing the tips are sterile. One end of the fiber is encased in a ferrule, which provides the permanent connection. A lens structure may also be utilized to focus laser light as it passes from a waveguide into the tip. The laser generation module may emit laser light in multiple wavelengths simultaneously and may also feature remote operation.
