Professional powerful laser pointer
Blue lasers can also be made directly using InGaN semiconductors, which can produce blue light without doubling the frequency. 450 nm (447 nm plus/minus 5 nm) blue laser diodes are still available on the open market. Some blue diodes can provide very high output. Like the NichiaNDB7K75 diode, it consistently outputs more than 5 watts of power when overloaded. These devices are brighter than 405 nm purple laser diodes with the same output. This is because the longer the wavelength, the closer it is to the maximum sensitivity of the human eye. Mass production of laser diodes, used in commercial equipment such as laser projectors, depends on price. High-performance versions of the 447 nm pointer are very popular now, reducing collimation and divergence for better optics.

The power spectrum ranges from 1mW to about 10mW and varies greatly with temperature. For hot or cold temperatures, it is usually in jump mode. This is because complex processes may require temperature ballasts and active cooling that cannot be installed on small mainframes. In addition, most small 593.5 nm green laser pointer operate in pulse mode, allowing you to use smaller, lower-power pumping diodes. The new 589nm yellow laser pointer is made using the more powerful and subtle harmonic method introduced by the DPSS laser system.Blue lasers can also be made directly using InGaN semiconductors, which can produce blue light without doubling the frequency. 450 nm (447 nm plus/minus 5 nm) blue laser diodes are still available on the open market.
