限幅器

A bridge limiter is a bridge circuit used as a limiter circuit.

桥式限幅器用桥式电路作为限幅电路。

The experiment and test results are in good accordance with the requirements and performance data of the limiter.

实验测试结果表明，限幅器完全达到技术指标要求。

The result indicates that the output power oscillates and weakens along with increasing input power,and its oscillation period depends on the distance between the medium and beam focal point.Limiter′s limiting ability will decrease if waist size of the incident Gaussian beam and the aperture size increase.With a fixed input power scope,medium′s best limiting position will move towards the focal point if waist size of Gaussian beam and the aperture size increase,but the best limiting position will change a lot with different input power scopes.

结果表明：限幅器的出射功率随入射功率的增加衰减振荡，其振荡周期取决于介质相对于光束焦点的位置；限幅器的限幅能力随入射光束腰半径和光阑孔径的变大而减弱；入射功率范围固定，入射光束腰半径和光阑孔径增大时，介质的最佳限幅位置向入射光束的焦点靠近，但是在某些入射功率范围内会存在多个最佳限幅位置；光限幅器的箝位输出功率随光阑线性透过率的增加存在线性增加和非线性增加两个不同区域，实际应用中应在线性增加区域确定光阑孔径的大小。

The secret is not to "think" about the thoughts but to allow them to flow through your mind,while keeping your mind free of afterthoughts.

其中的诀窍就是不要去&想&念头，让它流贯心头，保持心的自由和开放。
