Abstract

The generation in an optical-fiber waveguide of a spectral continuum spanning 29000 cm⁻¹ from the near infrared to the ultraviolet is reported. A Q-switched and mode-locked Nd:YAG laser is used to excite the fiber. An unexpected phenomenon is the generation of sum-frequency light derived from the pump frequency and the characteristic Raman Stokes frequencies of fused silica. This light is observed as visible light in cladding modes of the fiber.
