This laser has a higher performance factor than previous counterparts, enabling triple and quadruple layers for recording that would hold up to 128 gigabytes on each BD as opposed to the standard 25 gigabytes or 50 gigabytes. Furthermore, recording speeds could average 8x to 12x speeds. While the laser diode’s multi-layer BDXL specification will not be compatible with older players, the new SLD3237VF will be versatile in the use of more prisms and lenses. This will allow for more capabilities in electronic hardware design. According to one article, the flexibility of the optical unit may also drop costs. In addition to affordability, the implementation of this kind of blue laser makes it easier when it comes to future equipment upgrades.

A blue laser is a laser that emits electromagnetic radiation at a wavelength of between 360 and 480 nanometres, i.e. it emits blue light or light at the blue end of the spectrum. The light from blue lasers of shorter wavelengths is sometimes violet to the human eye, a distinctly different color. This is true, for example, of the most commercially-common blue lasers, the diode lasers used in Blu-ray applications, which emit 405 nm light that is distinctly violet.

Blue lasers are frequently semiconductor laser diodes based on gallium(III) nitride (violet color) or indium gallium nitride (often true-blue in color, but able to produce other colors, as well). Both blue and violet lasers can also be constructed using frequency-doubling of infrared laser wavelengths from diode lasers or diode pumped lasers.

After 10 years, Japanese manufacturers mastered the production of a blue laser with 60y mW of power, making them applicable for devices that read a dense high-speed stream of data from Blu-ray, BD-R, and BD-RE. Polish technology is cheaper than Japanese but has a smaller share of the market. There is one more Polish high-tech company which creates gallium nitride crystal – Ammono,[3][4] but this company does not produce blue lasers.
