A hand held laser device is disclosed including a handpiece coupled to a source of laser energy by an optical fiber cable. A bias tensile stress is exerted on the fiber when the fiber and outer sheathing or tube are straight in-line. The bias tensile stress reduces compressional stress on the fiber when the fiber cable is bent. Moreover, the fiber is coupled to a disposable fiber in the handpiece to output light from the laser to a target area. The two fibers are precisely spaced close to one another to permit substantial lossless transmission of light without lenses or other focusing optics. Further, precision bearing devices are provided at opposite ends of the fiber cable in order to reduce torque on the fiber.
