Abstract

The throughput performance of a ten-element transmission trap detector has been investigated at the laser wavelength 647.1 nm. The input beam of 1/e2 diameter 1.9 mm was studied at the output of the device in both s and p polarization states. The beam diameter was measured to change by less than 0.1 mm after undergoing ten internal reflections within the transmission trap detector for both polarization states of the incoming beam. The transmitted beam was observed to maintain a Gaussian distribution profile of the optical power intensity along the propagation direction, when compared with that of the input beam.
