Abstract: A three color laser system employs a diode pumped Nd:YAG or Nd:YLF laser to provide a green output beam and to pump two Ti:S lasers. One Ti:S laser emits a tunable red beam, while the second emits a near infrared beam. The near infrared beam is frequency doubled by a NLO device to provide a tunable blue output beam. The beams may be directed to separate optical fibers or to a single fiber. A reversed Cassegrainian mirror arrangement is used to combine a plurality of beams for transmission in a single optical fiber.
