used as ring-down cavity, this stable resonator has, firstly, more influence of misalignment of cavity mirrors on its measured reflectivity, but less of length misadjustment;
结果表明,这种稳定腔用作衰蕩腔,测量结果受腔镜角度失调影响较大,而受腔长失调影响小;
comparing with traditional stable resonator high-power tea co2 laser, it is always the key point to improve the optical beam quality as the same time guarantee the power of laser.
the beam parameter formulas of the stable resonator and numerical calculations are given. the propagation characteristics and the astigmatic compensation of the beam are discussed.
给出了显示象散作用的腔稳定图和稳定腔模参数公式,并作了数值计算。
the differences of the passive mode-locking by the sesam in the plane-concave stable resonator and the plane-convex unstable resonator lasers were experimentally compared and reasonably explained.
