How do DPSS lasers fill the ‘yellow gap’
iode lasers offer a vast range of wavelength options from the ultraviolet through the infrared. But, there is still one glaring hole in the visible spectrum between 520 nm and 633 nm. This region, which is often referred to as the “yellow gap,” results from the disparity between the upper range of InGaN diodes and the lower range in AlGaInP. When most people talk about Nd:YAG or Nd:YVO4 DPSS lasers, they are very familiar with the main 1064 nm laser line, and for a good reason, since it is the most efficient tra… Read More
