Abstract

A simple and inexpensive method to perform high resolution spectral studies of the green-yellow pulse shapes of a CuBr laser is presented. The radio-frequency (RF) spectrum of the temporal shape of the detected signal is called `pulse-shape spectrum (PSS). The individual 510.6 nm (green) and 578.2 nm (yellow) PSS are studied in the range 20 - 500 MHz with 1 MHz resolution. The RF spectral analyses of the compound signal (the weighted sum of the two pulses, one of them being delayed with respect to the other one) reveals that the coherence properties of the spectral components are dependent both on the pulsed mode excitation and the optical modes supported by the optical cavity.
