Abstract

We demonstrated experimentally a new method for generation of linearly chirped light waves with almost perfect linearity over a broad range of about 800 GHz. The external modulation method that we adopt can maintain frequency jitters at a very low level by avoiding relaxation oscillation effects which are an intrinsic property in intra-cavity modulation methods. The linearly chirped light could provide an excellent time-frequency mapping tool for wide-range applications.
