Developments of a space-borne stabilized laser for DECIGO and DPF
نویسندگان
چکیده
As a light source for the space gravitational wave detector DECIGO/DPF, we have developed space-borne frequency-stabilized lasers. The light source was an Yb-doped fiber laser with the wavelength of 1030nm. The frequency of the Yb-fiber laser was stabilized in reference to the saturated absorption of iodine molecules so as to suppress the frequency noise down to 1 Hz/rtHz at 1s. We will report the second version of breadboard model of the frequency–stabilized laser for DPF. Keywords-component; frequency-stabilized laser, gravitational wave detection, space-borne laser

Gravitational Wave Background and Non-Gaussianity as a Probe of the Curvaton Scenario
We study observational implications of the stochastic gravitational wave background and a non-Gaussian feature of scalar perturbations on the curvaton mechanism of the generation of density/curvature fluctuations, and show that they can determine the properties of the curvaton in a complementary manner to each other. Therefore even if Planck could not detect any non-Gaussianity, future space-ba...

Control the laser beam hazards for class IIIB and IV laser is concluded: engineering and executive controls. In executive control, when laser beam enters to the free space, the controlled area must be identified to protect people and control the radiation exposure limits. Given the fact that the laser light of the laser is entering the environment, the identification of the area under control i...

The development of a space-qualifiable 2-micron laser is beneficial to both the Exploration and Earth science technology goals. Recently, significant advancements in the laser development have been made under the Laser Risk Reduction Program. One Joule per pulse energy was achieved by a Master-Oscillator-Power-Amplifier (MOPA) system. To our knowledge, it is the highest recorded energy at this ...
متن کاملUnification of Surface Enhanced Raman Spectroscopy of Dyes Using One Pot Synthesized Stabilized Ag Nanoparticles
stabilized Ag Nanoparticles (NPs) were synthesized using Lee-Meisel method under three different conditions in an oil bath. UV-Vis spectroscopy of the Ag NPs showed a Localized Surface Plasmon (LSP) band around 430 nm, indicating Ag NPs had a size range around 40 nm. To fabricate a surface Enhanced Raman Spectroscopy (SERS) substrate, LSP properties of Ag NPs was employed with the goal of detec...
متن کاملStructural basis for the recognition of two consecutive mutually interacting DPF motifs by the SGIP1 μ homology domain.
FCHo1, FCHo2, and SGIP1 are key regulators of clathrin-mediated endocytosis. Their μ homology domains (μHDs) interact with the C-terminal region of an endocytic scaffold protein, Eps15, containing fifteen Asp-Pro-Phe (DPF) motifs. Here, we show that the high-affinity μHD-binding site in Eps15 is a region encompassing six consecutive DPF motifs, while the minimal μHD-binding unit is two consecut...
