ABSTRACT:
A holder for the rear mirror of a laser generator has a pressure balance orifice formed in the block supporting the rear mirror in the mirror mounting member. The orifice equalizes the pressure between the chamber through which the laser passes and a chamber formed by the support block and the rear mirror. An additional pressure balance orifice is formed in the support block between a chamber formed by a power monitor supported in the support block and the chamber formed by the rear mirror in the support block, thus equalizing the pressure between these chambers. Another pressure balance orifice is formed in an addditional block supporting a total reflection mirror in the mirror mounting member, between the laser chamber and a chamber formed by the total reflection mirror in the block. Pressure is thus equalized between these two chambers. The rear mirror holder is removably mounted on the mirror mounting member by means of a separating member which may be wedged between the rear mirror holder and the mirror mounting member to separate them.
