Power Sensor Assembly

The Model 602-0107 Power Sensor offers a compact, cost effective source for taking CW/Multimode power output readings from your Nd:YAG laser operating @ 1.064µm. This sensor is designed to operate Air or Water cooled, however most applications will not require water cooling. Extreme care must be given to ensure the maximum power exposure duration (5 min) Air-cooled is not exceeded. Doing so will result in critical damage to the sensor itself. Additionally, this sensor must remain mounted to the heat sink plate at all times to assist with heat dissipation.

NEVER PLACE THIS SENSOR IN THE PATH OF A Q-SWITCHED OR FOCUSED BEAM!
ALL POWER READINGS MUST BE CW/MULTIMODE AND NON-FOCUSED.

This assembly offers two methods for obtaining power readings from your laser. The "fork" plate allows this assembly to hang from the F-theta or final lens for non-focused power readings. If your system will not allow for this type of mounting, simply place this assembly at the work piece out of focus.

The second option for power readings can utilize the "stand" to which the sensor is mounted. Simply remove the fork plate by removing the two large thumb screws. You will now be left with a right angle plate which can be positioned outside the front mirror on many lasers. This will allow you to verify the power output from the laser resonator and then compare it to your power reading at the work piece. Completing these two
steps will allow you to verify any significant power differences. This will also allow you to determine if the laser is producing factory specified power readings for your system and if there are alignment or damage issues to the front optics such as beam expander lenses, galvanometer mirrors, F-Theta lens and dust window.
