As a manufacturer based in China, we focus on diode stacks and spare parts for laser diodes. You can find comprehensive information about their appearance, specifications, interchangeable tips, factory pricing, and shipping options from China.

We also provide free consultations. Below are examples of diode stacks that can be installed in your older diode laser handpiece. COMMON MALFUNCTIONS AND CAUSES OF FAILURE IN THE 808NM LASER STACK include burnt-out laser emitters, failure to emit light, black spots on the stack bars, and visible burns at the solder joints connecting the bars. The primary reason for these issues is overheating, which is influenced by the water temperature within the device. The ideal temperature is 23 degrees Celsius; exceeding this can lead to faster failure of the diode stack. Additionally, there may be issues with the electronic components. Each bar requires a specific voltage, and the voltage signal must conform to a specific shape. Physical damage, like cracks in the outer glass, can also worsen these issues. Over time, the bars may "age," leading to decreased effectiveness. In such cases, replacing the emitter with a new one is essential. A COMMON QUESTION WHEN SEEKING LASER REPAIR is, 'the diode laser has stopped flashing, and there is no sensation during the use of the handpiece.' It’s crucial to visually inspect the inside of the diode laser handpiece through its window. If you see black spots or stains inside, there is a 99% chance that your laser bar has burnt out.
