Abstract: A method and apparatus for constructing a snow shelter are disclosed. A slip form allows snow or ice crystals to be compacted in situ in large continuous blocks. Each block is built upon the previous as the slip form is rotated incrementally around a generally horizontal axis (175). The slip form is a convex shape. The convex shape, or profile, is tailored to the size and shape of the shelter desired. The resulting shape of the snow shelter is a surface of revolution of the profile of the slip form around a horizontal axis. Variations of the shelter's shape are explained herein. Various embodiments are described herein. Some of the advantages of the embodiments include: faster and more efficient construction, simple operation, and tailored size and shape of the finished shelter.

Abstract: Embodiments of systems and methods are provided for a tunable laser device. The tunable laser device may include a tunable Bragg reflector that allows its wavelength to be tuned via temperature and/or pressure. This Bragg reflector may include holographic material in which a Bragg grating may be formed comprising parallel fringes of alternating index of refractions. Temperature and/or pressure changes may be effected in the Bragg reflector by, for example, a thermoelectric cooler and/or piezo transducer.
