532nm DPSS laser pointers can cost well under $100, but 473nm DPSS lasers can easily cost $500, even though they use the same DPSS techonlogy. Why is 473nm so much more expensive? Does the IR diode use a wavelength where the semiconductor material for that diode is more expensive, or does the frequency doubler crystal for the 473nm wavelength use a material that's much more expensive than the material used for the frequency doubler crystal for the 532nm wavelength? Or is it priced high just because it's considered a luxury item? Like when they first came out (so they were new tech and high price was justified) only rich people could afford them, so as more and more rich people bought them they began to be seen as luxury items, so to keep up that appearance of luxury all the manufacturers artificially keep the price high (kinda like the manufacturers of BMWs and other even more expensive luxury cars)?
