• Blue laser output exceeds 120 milliwatts using all-optical cavity-locking scheme

    A research team at the University of Central Florida`s Center for Research and Education in Optics and Lasers (CREOL; Orlando, FL) recently demonstrated a signal resonant-sum-frequency laser emitting at 467 nm. The diffraction-limited output power was 120 mW. In this device, the intracavity field of a 1047-nm Nd:YLF laser is summed with a second input from an 845-nm semiconductor tapered amplifier using KTP. Conversion of the 845-nm input to blue light is maximized by locking its frequency to an

Conversion of the 845-nm input to blue light is maximized by locking its frequency to an optical resonator containing the KT¥crystal. Passive optical techniques, recently developed at CREOL, are used to maintain a stable frequency lock.
