摘要
Lasers have been made from Nd: YAG single crystals grown directly in the form of fibers. These fibers, 50 to 80 μm in diameter and 0.5 cm long, were pumped at 0.8 μm wavelength by a single AlGaAs LED. One milliwatt output power, plane polarized in a single mode at 1.064 μm wavelength, has been achieved in continuous room-temperature operation, and a self-contained laser-LED package has been demonstrated. Construction and operation of the devices are described. Improvement by a factor of two in operating efficiency using straightforward techniques is predicted to yield 1 mW output at a pump diode current of ∼ 75 mA and laser threshold at ∼ 10 mA pump current. © Taylor & Francis Group, LLC.
