Our company is a Chinese manufacturer that specializes in diode stacks and provides spare parts for laser diodes. You can find details 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 a burnt-out laser emitter, failure to emit light, black spots on the stack bars, and visible burns at the solder joints connecting the bars. The primary cause of these issues is overheating, which is influenced by the water temperature within the device. The ideal temperature is 23 degrees Celsius; exceeding this can accelerate the failure of the diode stack. Additionally, there may be problems with the electronic components. Each bar requires a specific voltage, and the voltage signal must conform to a particular shape. Physical damage, such as a cracked outer glass, can also contribute to these issues. Over time, the bars may "age," leading to reduced effectiveness. In such cases, replacing the emitter with a new one is necessary. 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 important to visually inspect the inside of the diode laser handpiece through its window. If you observe black spots or stains inside, there is a 99% chance that your laser bar is burnt out.
