Abstract
For some kinds of industrial applications like laser photochemistry, high pulse power and fine tunability is required for a laser system. A cw oscillator and pulse dye amplifiers system is one method to generate high power laser pulses with narrow spectral bandwidth enough for laser photochemistry. In this paper, we report that the spectral sidebands occur in the process of amplification pumped by CVLs of which the intensity fluctuated. The spectral profile fluctuations and mode beats are deduced to cause these fluctuations. According to the rate equation analysis, the DL waveform is modulated by the CVLs, and the frequency sidebands are generated, and its frequency bandwidth is several GHz. Since the spectral bandwidth of the DL is usually a few 100 MHz, the bandwidth and the level of amplitude modulation of the pumping laser are very important. This modulation may be reduced by multi pumping beam irradiation or other methods.
