This is 808nm 4W fiber laser source with LCD screen, can display current laser power and working current. The output power is adjusted by 5 buttons. The 808nm laser is a near-infrared laser, we can only see very small red dots.
The high-power laser source is based on a high-performance semiconductor laser chip.
It uses a professionally designed constant current drive and TEC control to ensure safe and stable laser operation, and 105/125um fiber-coupled output. The power fluctuation is <1%, and the spectral stability is better than ±3nm.
