Laser beam diagnostics

Macken Instruments‘ model 23-S consists of seven beam probes and one fabric case. Each beam probe covers a different sensitivity range which extends from 200 w/cm2 to 0.05 w/cm2. The five beam probes correspond to surfaces #1, 2, 3, 4, 5, 7, and 8 described in Macken Instruments’ thermal image plate data sheet.

Each beam probe is 1/8” thick, 1 ½” wide, and 6” long. The end of each probe is tapered to 1/32” thickness so that the thermal sensitive surface can be brought close to optical parts.

The CO2 Spectrum Analyzer is a unique grating spectroscope which simultaneously displays all the lasing transactions of a CO2 laser. It is calibrated both in wavelength and rotational line designation to permit easy identification of 140 possible laser transitions between 9.1 and 11.3 µm. These transitions are visually displayed through the use of a UV excited thermal sensitive screen which darkens in the area struck by the IR laser beam.

The spectrum analysis screen has a response time of 1/4 seconds and permits the instrument to resolve all the CO2 rotational lines. The Model 16-A is light, portable and can easily be introduced into laboratory setups.
