Green Vs Blue (price PoV)

Hello...

Why is it the blue lasers (445nm) are much much MUCH cheaper than the green ones (532nm) for example:

1w blue (445nm) costs about 200$-300$
while a _
500mw green (532nm) can reach more than 500$

one more thing...

i have noticed that DL(dragon lasers) has a very high price tag on there lasers compared to other companies or website like DD. If both of them are giving you the same OP power then whats the difference.

:thanks: in advance

The 445nm ones are so cheap because a certain company that shall remain unmentioned due to legal issues needed them for a product of theirs, and since they needed them cheap, they got them cheap. (They had to be very affordable in order to be put to the use said company needed them for).

This product of theirs contains 24 of high-power 445nm diodes, and since this product is very reasonably priced, there are quite a few laser enthusiasts who purchase these products for the sole purpose of removing said diodes.

(vague? The forum got into legal trouble over this at one point, so I'm not mentioning the name or company)

It is because blue ones are a lot easier to make.
Take for instance yellow 589nm, that color is very hard to make and for 50mw-100mw you will have to give about 1000$ or even more.
It just depends on how easy is to make them.

short version
blue = mass produced + easier to make = cheaper /per mw
green = different method of making the component + not mass produced = more expensive

wasn't the blue diodes used in projectors? can't put my finger on which company though...:thinking:

why would ©@$İő want legal claims with this forum?

Green lasers ARE mass produced. Why else would everyone and their dog have one these days?

First, read up on the difference between diode and DPSS technology.

If you really want to appreciate the difference between a cheap laser from DinoDirect and a laser from one of the high end companies, you should purchase one from each of similar specifications and compare.

Otherwise, you can look through the reviews section for names like Laserglow, Novalasers, Optotronics, CNI.

That is not to say that the higher end companies should not drop prices on some of their items. It's been several years since I bought my first >100mW green laser (Novalasers X105 $200) and today the price is pretty much the same.

Also, it's not all about power. Beam quality, stability, IR filtration, and the quality of components is important, too.
Now that the cheap, generic lasers have taken over the market, I think people have forgotten that green lasers can have less than 2mRad beam divergence, or at least output the power it was rated for without mode hopping, flickering, or spewing out 15% IR.

because "users" are taking apart their products to harvest "dangerous components inside"
