Summary of 780nm Laser
Low visibility: 780nm light is near-infrared, making it invisible to the human eye. This can be both an advantage and a disadvantage. While it doesn't interfere with human vision, it requires specialized equipment for detection and alignment.
Moderate cost: 780nm lasers, especially direct diode lasers, are generally affordable compared to some other laser wavelengths. However, the cost can vary depending on factors like power output, beam quality, and additional features.
Wide range: 780nm lasers have a wide range of applications due to their deep tissue penetration and high resolution. They are used in fields such as:
- Medical applications (OCT, laser therapy)
- Industrial applications (material processing)
- Scientific research (atomic physics, spectroscopy)
- Optical communication
