Nowadays, the More durable transmitted red light air, dust, water vapor, so the light path can be seen to need more power. The first red light was released in the early 1980s. Red laser pointer, wavelength 630-670nm green laser pointer is more for longer. On top of that, despite the lower total power, blue light heads feature much higher power density than CO2 lasers. This means you have a universal lasers that can process any material. Ultimately, the biggest perk of blue light is that metals efficiently absorb blue light beams. Opt Lasers’ blue light diode modules and laser heads are often a superior choice to alternative solutions, as they offer high reliability, lower power consumption and can process a wider range of materials, metals included. In many applications, it is also advantageous to incorporate a blue light instead of certain IR lasers like fiber lasers and CO2 lasers. The light beam produced is temporally coherent and can be well-collimated, which allows it to have numerous applications in industry and science. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard. It is probably not as much preferred as an astronomy lasers, because brighter colors would make an object more visible in the sky. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. Blue Laser pointer with 405 nanometers wavelength of light. ![]()
