Abstract
One of the exciting Challenges in recent years was to develop a coherent radiation source which would bridge the energy region between the infrared and the microwaves. We have achieved this objective with the use of two high power CO2 TEA lasers and a non-collinear phase matching technique in a crystal of GaAs.1 Our results represent one of several methods which may be used to do this.2 At present, our technique gives a broadband spectrum which spans over two decades from 70µm to 1 cm, with resolution of the order of 10−2 cm−1 and capable of peak power levels which vary from ~ 1 watt to ~ 10−4 watt from the short to the long wavelength regions, respectively.
