Performance comparison of Laser Diode-Pumped Liquid Laser between Single Gain Host and Double Gain Host
Flowing circulation can emanate heat of liquid laser with single gain host, but it also arises heat gradient in the flowing direction. Double gain host can emanate heat effectively and avoid heat gradient in flowing direction, and possesses better performance. The heat character and far-field facula of liquid laser with single gain host and double gain host at the same gain length were simulated, and then compared. The result indicates the performance of the double gain host is much better than that of the single gain host: the peak intensity of far-field facular is enhanced by ten times, and the energy concentration extent and beam quality are both enhanced evidently.
