To fix issues with a dim red or green laser pointer, consider the following possible causes: batteries that have outlived their lifespan, a dirty lens, speckle effects from rough surfaces, an aging or damaged diode, and pointing the laser at anti-glare surfaces. Dimming often occurs when the laser pointer's batteries are depleted or the lens is dirty. The dim appearance can be due to the laser being pointed at anti-glare surfaces or experiencing speckle effects. I bought a driver that matched the current rating of the diode and connected it all up. This blog explores the common component-related causes of laser beam instability and offers insights on how to diagnose and address these issues. If I turn it off for a bit, it's bright, then dims again. I tried reinserting my batteries, rotating the body thinking there must be some loose current. Does anyone know what might be wrong? My best guess is, that it's using a distributed.
