Abstract

The design of the frequency converter is proposed which exploits laser pulses with changed state of polarization. The use of such pulses as a fundamental wave source of an extra-cavity doubling crystal is shown to result in the large conversion efficiency and to monitor the shape of the generated harmonic pulse. Our study demonstrates the converter to be capable of pulse shortening due to the temporal variation of the direction of polarization of the pulse at the fundamental wavelength which occurs in the same device.
