ELECTRO-OPTIC MODULATOR

An electro-optic modulator (EOM) for altering an optical path length of an optical field is described. The EOM comprises first and second Brewster-angle cut nonlinear crystals having a first and second optical axis. The optical axes are orientated relative to each other such that when an optical field propagates through the nonlinear crystals it experiences no overall deviation. The nonlinear crystals are also arranged to be opposite handed relative to the optical field. The EOM has the advantage that its optical losses are lower when compared with those EOMs known in the art. In addition, the EOM can be inserted into, or removed from, an optical system without any deviation being imparted onto the optical field. This reduces the levels of skill and effort required on the part of an operator. The described method and apparatus for mounting the nonlinear crystals also suppresses problematic piezo-electric resonances within the nonlinear crystals. 1. An electro-optic modulator (EOM) suitable for altering an optical path length of an optical field , the electro-optic modulator (EOM) comprising:a first Brewster-angle cut nonlinear crystal having a first light input axis and a first light output axis;a second Brewster-angle cut nonlinear crystal having a second light input axis and a second light output axis, wherein the first light output axis is coincident with the second light input axis between the first and second Brewster-angle cut nonlinear crystals; and the first and second Brewster-angle cut nonlinear crystals are arranged to be opposite handed relative to the optical field propagating through the first and second Brewster-angle cut nonlinear crystals;a mounting apparatus that provides a means for locating the first and/or second Brewster-angle cut nonlinear crystals, the mounting apparatus comprising a first clamp section having one or more adjustable crystal holders and a first electrically insulating base plate attached to the first clamp section; anda layer ...

Purging system for a laser system

A purging system for a laser system is described. The purging system comprising a cartridge that houses a desiccant material and which is configured for removable mounting with an enclosure of the laser system. The cartridge comprising a first mesh layer that provides a means for a fluid to flow to the desiccant material housed within the cartridge. The purging system further comprises a membrane located over the first mesh layer. The purging system therefore provides a mean for passively purging the laser system and so its operation does not require the employment of a pump. The employment of the removable cartridge also has the advantage that the downtimes of the laser system with which it is deployed are reduced during periods when it is required to dry or replace the desiccant material.
