Terahertz Laser Power Output Increased by 80%

Recently, research teams from Sandia National Laboratories and the University of Toronto have made a breakthrough in miniature terahertz light sources, successfully increasing the power output of the terahertz laser by 80 percent, Imaging and chemical testing and other fields are widely used.

At present, the project has been favored by NASA for measuring oxygen content to explore interstellar media components. As the terahertz 100mw laser pointer source has the problem of emitting laser light in the opposite direction, resulting in its actual output efficiency is low, at least half of the energy is wasted, making the application is limited.

In order to solve this problem, the research team adopted a new structural design. The use of quantum cascade laser to form "standing wave", and in the standing wave to add cracks, so that terahertz laser can be out of the waveguide, and the opposite direction of the band coincidence to increase the laser intensity. The device successfully guided 80% of the laser intensity in the right direction. At the same time, the design also solves the traditional mirror caused by laser synthesis loss of the problem, for the terahertz laser efficiency is very important.

The design further enhances the terahertz laser power, but is still partially wasted. The future also need to improve the overall performance of the blue laser pointer beam, so as to obtain a higher quality laser beam.
