In June 1984 a conference on visible and IR tunable solid-state lasers was held in La Jolla, California. The proceedings were published as the first volume of this series, Tunable Solid State Lasers •. The emphasis of this meeting focused on discer

Bidirectional (mutual) injection locking was demonstrated with solid-state lasers, producing significant improvements over traditional single-direction injection locking. Each laser element shares part of its output with other elements in bidirection

Pure yttrium vanadate crystals (YVO4) have optical properties ideal for polarizers in the mid-IR spectrum. YVO4 is highly transmissive from 400 to 3800 nm and is optically useful to 5 micrometers . YVO4 is a positive uniaxial crystal with a birefring

Surface damage thresholds of polished calcite crystals were measured with a pulsed ruby laser at the wavelength of 694.3 nm. Three grades of calcite used for laser polarizers were tested: Grade A, Schlieren-Free, and Scatter-Free, as characterized by

The construction and operation of a selective thermal emitter is described when attached to a light pipe or optical waveguide. The emitters studied are single crystals of rare-earth aluminum garnets involving ytterbium, erbium and holmium, and the li

A pulsed erbium garnet laser (30 Hz at 2.78 micrometers ) was used to characterize cutting on various soft tissues. Bovine heart, porcine liver and chicken breast were cut, and the resultant craters cut were microscopically examined. The variation of

Thermal and stress lensing effects have been measured in a Cr,Er:YSGG rod by observing a transmitted 1064 nm Nd:YAG beam diverging from an operating Cr,Er:YSGG laser. The results compare favorably with theory and estimated thermal-optic properties of

Human enamel and dentin were cut using a 2.8 micrometers erbium laser beam in conjunction with water spray. Ablation rates of the order of 0.14 mm3/s were achieved for both tissues at 4 W average power. An ablation threshold of 0.28 W was determined
