热不敏感腔的解与特征

SOLUTIONS AND CHARACTERS OF THE THERMAL-INSEN-SITIVE RESONATOR

本文发展了变换圆图解处理方法,并运用它求得了热不敏感腔的一般解:σ_1圆与π_f圆相切,清晰地阐明了它的主要特征;同时,澄清了有关它的特证的若干不确切的看法,进而,还求得了最佳热不敏感腔的特别解:g_1g_2=1/2;L_2=0或L_2=R_2。

In this paper the transformation-circle diagrammatic approach is developed. Using this method, the general solution of the thermal-insensitive resonator is derived, that is, the σ1 circle is tangential to the p1 circle. Its main characters arc elucidated clearly. Some inaccurate current points of view on its characters are made clear. Furthermore, the special solution of the optimal thermal-insensitive resonator is obtained, that is, g_1~*g_2~*=1/2; L2 = 0 or L2=R2.
