A light-based medical scope system includes a semiconductor diode pump source, a multiplexer that combines diode outputs to generate an optical signal. First and second waveguide structures guide the optical signal with a coupling loss of about 5dB or less through a scope adapted for insertion into a patient's body. A focusing element coupled to a distal end of the second waveguide structure is adapted to focus the optical signal onto the patient's body. A housing includes a base portion, a flexible portion, and a head unit mounted onto the flexible portion. The focusing element is located within or passes through the head unit, and the base portion includes a mechanical control for manipulating the flexible portion. In one embodiment, a waveguide structure directs an output beam of 1.7 microns or more to perform a differential measurement on patient blood with the result displayed on an associated monitor. |
