7B1 - Ruby laser loss measurement by comparison of R1, R2 thresholds
No full textA simple method of measuring the losses of a ruby laser resonant cavity has been developed in which the thresholds for R1 line and R2 line operation are compared. A quartz birefringent filter is placed in the cavity with quartz disk cut to allow Brewster-angle operation and of such a thickness that the separation between pass bands of the filter analyzer combination is 2.8nm. The analyzer, placed between the filter and the output mirror, consists of a stack of fused quartz plates at the Brewster-angle. A known loss is introduced into the cavity by means of a plate inclined to the laser beam at a known angle. With the filter set for R2 operation the threshold is adjusted to a suitable value by rotating the loss plate to give an attenuation L2 pass. The filter is then reset for R1 operation and a different (larger) attenuation L1 must be introduced by the loss plate to raise the R1 threshold to the same level. An analysis of the threshold populations of the 2E levels shows that the losses of the cavity due to all sources of loss other than the loss plate may be obtained from a plot of log L1, against log L2
