Three Points to Check When Laser Power Drops

When laser power unexpectedly drops, the problem is usually with the optical path.By focusing on three key areas--output mirrors, reflection mirrors, and focusing mirrors--the guidebook provides practical inspection methods to help users quickly locate the problem and restore equipment performance.Keywords are naturally incorporated, and the steps are easy to understand.

Why does the number of nodes affect output power?

When a laser is operating, the optical path is like its "vascular system." If there is dust, misalignment, or aging at any point, it's like a blockage in a vein, weakening the energy transfer.Don't rush to send your device in for repair. Instead, try the following three steps to save time and money.

First stop: The "check-up" for the mirror.

The output mirror is the first barrier the laser light must pass through, and problems here can cause the laser's power to be "choked off.

Inspection priorities.

Use a bright flashlight to look for fogging, scratches, or burn marks. A flaw the size of a grain of rice can reduce the power of the mirror by 20 %.

• Dab a cotton swab in alcohol and wipe the rim to test for cleanliness. If you see a gray-black stain, it's time for a thorough cleaning.

• When reassembling, be careful that the gasket is not deformed. Many experienced mechanics have been tripped up by this small detail.

The second part: the "focus game" of the mirror assembly.

The mirrors are like relay runners: a deviation of just 0.1 millimeters could cause the laser to "run off the track.

The technique of tuning.

Prepare thermal paper: Reduce power and print a test dot. A perfect dot should be a clean, sharp-edged circle.

• First adjust the vertical angle and then the horizontal angle. It's like adjusting the antenna of an old-fashioned TV--patient fine tuning is more reliable than hoping for a miracle.

If the frame keeps shifting, check to see if the anti-loosening glue on the screws has lost its effect.

Thirdly, the "invisible killer" of the focusing lens.

This lens, which is closest to the work piece, often silently bears the brunt of smoke and splatter.

Maintenance points.

• Clean the machine at least twice a week with a vacuum cleaner. Don't wait until the dust has hardened into clumps.

• When cleaning, use the "coil" method, and don't rub randomly, or you may scratch the coating.

• If the depth of the etching suddenly changes, chances are that the lens has been warped by heat.

The little tricks of everyday maintenance.

Adopting these three habits will make the optical system last half a year longer.

• Blow the optical cavity with compressed air before shutting down.

• In the rainy season, place dehumidifiers near the equipment and turn them on when the humidity exceeds 60 percent.

• Keep a record of how long each lens has been in use.

By following this method, most power loss problems can be solved.If it still doesn't work, contact the manufacturer--it may not be Kuanlu's fault!
