Abstract:

By closely working with Prof. Ding"s group at Lehigh University, PI proposes to take a revolutionary approach to THz generation based on difference-frequency generation. Such a nonlinear process will take place inside the cavity of a dual-wavelength Yb:YAG laser. PI plans to demonstrate dual-wavelength operation of CW and Q-switched Yb:YAG lasers. PI"s goal is to reach the output powers of at least 1 W at each of the dual wavelengths. Subsequently, PI will achieve efficient conversion between the optical waves generated by the dual-wavelength laser and a THz output outside a Q-switched Yb:YAG laser cavity. The highest output power is expected to be 200 nW at 1 THz. PI is going to carry out feasibility studies on intracavity THz generation based on the performances of the CW and Q-switched Yb:YAG lasers tested and THz generation achieved outside the laser cavity. According to PI"s estimate, it is feasible for her to improve the THz output power to 1 mW. Moreover, she will be able to achieve the tuning range of 150 GHz - 1 THz, the linewidth of 100 MHz, and the repetition rate of 10 kHz. PI will also develop a concrete plan for identification and detection of biological agents.
