摘 要：Alkali laser has been one of the most promising paths to high energy laser during past dozen *** the first group realized DPAL and XPAL lasing in China,we had done lots of theoretical and experimental works to further clarify the mechanism of alkali lasers,such as exploring scaling parameters design balance and MOPA configuration amplified spontaneous emission suppression in DPAL based on our self-developed fast converging algorithm,XPAL’s continuous wave operation threshold,performance degradation of VBG narrowed diode laser array and stacks due to conductive thermal flow,heat deposition induced gas dynamic parameters variation estimation,local atomic number density change measurement with single frequency tunable diode laser,ionization and other higher level nonlinear effects with opto-galvanometer *** on above research works,preliminary considerations and conclusions for alkali laser scaling were given.
