    Abstract

    We review new developments with a new laser host material, YCa4O(BO3)(3) or YCOB. Lasers based on this host material will open new opportunities for the development of compact, high-power, frequency-agile visible and near IR laser sources, as well as ultrashort-pulse sources. Efficient diode pumped laser action with both Nd-doped and Yb-doped YCOB has already been demonstrated. Moreover, since these materials are biaxial and have high nonlinear optical coefficients, they have become the first laser materials available as efficient self-frequency-doubled lasers capable of providing tunable laser emission in several regions of the visible spectrum. Self-frequency doubling eliminates the need for inclusion of a nonlinear optical element within or external to the laser resonator. These laser materials possess excellent thermal and optical properties, have high laser-damage thresholds, and can be grown to large sizes. In addition they are non-hygroscopic. They, therefore, possess all the characteristics necessary for laser materials required in rugged, compact systems. Here, we summarize the rapid progress made in the development of this new class of lasers and review their potential for a number of applications.
