Low-cost and compact blue/green lasers are desired for applications such as micromachining, laser display, underwater communications, high-density optical data storage, and medical diagnostics recently. Therefore various type of blue and green lasers have been studied, especially for intracavity frequency doubling of the diode-pumped solid-state laser, which can generate high blue/green powers with long lifetime. Unlike the green laser, which is originated from a four-level laser, the blue laser belongs to a quasi-three-level system, so it is more difficult to develop the blue laser source. The purpose of this experiment is to develop a high power and high efficiency blue laser with simple structure so that it can easily be commercialized. Furthermore, it is a very cost-effective approach to develop such solid-state lasers, if the laser output characteristics can be estimated precisely using software simulation. We used an optics software GLAD to model our four-level and quasi-three-level Nd:YAG laser systems. In experiment, we developed a blue laser system with a cavity length of 4 mm and with 71.7 mW of blue output power. Besides, we have succeeded in using GLAD to model a Nd:YAG plane-parallel laser cavity, which has an optical conversion efficiency of 68%. Finally, we designed an effective lens duct with a coupling efficiency up to 80%, even if there is no AR coating on lens duct¡¦s input or output facets.

This study was designed to test the hypothesis that the level of first summer mortality in blue grouse is determined by the condition of the hen and that this in turn determines the level of subsequent fall and spring densities. Early mortality was studied in a series of field and aviary comparisons of chicks on, or from, two areas of Vancouver Island that were in different stages of vegetative succession, following logging and burning. The summer recruitment each year was then compared to annual trends and mortality rates as determined for the breeding populations. No relevant differences were found in the pre-hatch parameters of recruitment (clutch size, fertility, and hatchability) between areas or years. No differences were found in the survival of young between areas, but differences were found between years. There were always sufficient young produced into the fall period to replace the annual losses in the breeding population. The major conclusions are: (1) early mortality does vary between years but does not vary between different habitat types or between areas with different breeding densities, (2) variations in early mortality between years are a result of as yet undetermined parental influences, and (3) this mortality is involved in the regulation of fall numbers, but is not involved in the regulation of subsequent breeding levels in established populations. / Science, Faculty of / Zoology, Department of / Graduate
