By placing an intracavity Fabry-Perot transmission etalon between quarter-wave plates it is possible to operate it at normal incidence without spurious oscillation due to reflections from the etalon. The insertion loss and reduced finesse associated with a tilted etalon are thereby avoided. This technique will allow the use of longer etalons thus allowing much greater mode selectivity.
