The monolithic ring approach to building powerful, highly-coherent laser sources is been well proven at the two wavelengths of 1064 nm and 1319 nm. The commercial market and the thus technological value of this laser design increased if more wavelengths were available at the same high power and extreme coherence. This research explores lasers based on the monolithic ring resonator design at a number of wavelengths other than 1064 nm and 1319 nm. These lasers may applications in absolute-distance interferometry, astronomical instrumentation for detection of astronomical millimeter waves, atomic clocks and precision metrology using specific near infrared and visible wavelengths. The Phase I objective is to powerful, single-frequency, diode-pumped laser oscillation on a number of laser lines that have not yet been used commercially. Two techniques are employed. First, using Nd:YAG, the research uses wavelength-selective coatings to get as many wavelengths as possible. Second, lasers at two quasi-three level laser lines - Nd:YAG at 946 nm, and Yb:YAG at 1030 nm - are constructed by using diffusion-bonding to create monolithic resonators with doped and undoped regions. The range of single-frequency laser lines which are available is expected to be expanded. Phase II will be the design of lasers at wavelengths identified in Phase I.

单片式环形方法构建强大的高相干激光源在1064 nm和1319 nm两个波长下得到了很好的证明。 如果在相同的高功率和极端相干性下有更多的波长可用，则这种激光器设计的商业市场和因此的技术价值增加。 本研究探讨了基于单片环形谐振腔设计的激光器，其波长范围为1064 nm和1319 nm以外。 这些激光器可以应用于绝对距离干涉测量、用于探测天文毫米波的天文仪器、原子钟和使用特定近红外和可见波长的精密计量学。 第一阶段的目标是在一些尚未商业化的激光线上实现强大的单频二极管泵浦激光振荡。 采用了两种技术。首先，使用Nd：YAG，该研究使用波长选择性涂层来获得尽可能多的波长。第二，激光器在两个准三能级激光线- Nd：YAG在946 nm，Yb：YAG在1030 nm -通过使用扩散键合创建单片谐振器与掺杂和未掺杂的区域。 单频激光谱线的范围有望扩大。 第二阶段将是在第一阶段确定的波长上设计激光器。
