Widely Tunable and High-Duty Terahertz p-Ge Laser in a Closed-Cycle Refrigerator

摘要

The R and D objectives of this project are to increase the duty cycle and operation temperature of the fa-IR p-Ge laser, to design and test a tunable frequency-stabilized laser for THz sensing and spectroscopy, and to obtain cryogen-free operation. All grant funds were allocated for the purchase of a state-of-the-art closed-cycle refrigerator system to be used in attaining the objectives. Support for other research expenses and salaries comes from the National Science Foundation and subcontracts on Zaubertek SBIR/STTR projects.
