BLU-RAY LASER AT KD FOR >$550???

[robo21]

I'm familiar with red and green lasers but this sounds ridiculously expensive for a laser, especially at these power levels. The 20mw is over $700.

Does anyone know why these are so expensive? Are they more efficient or powerful for the same mw's or is it just the novelty of the beam color?

Thanks in advance!

I see those today too and they have a 50mw version too Clickhere>> http://www.kaidomain.com/WEBUI/ProductDetail.aspx?TranID=4625

What's the deal with the blue lasers? Are they any more potent or what? Why the high premium for blue?

 

[warlord]

Hahahaha!

Nah, they just look cool.

 

[pyrokid3]

Blue lasers are harder and more expensive to produce. And they look really cool too :naughty:

 

[robo21]

For the price difference green definitely seems the way to go.

i didnt see the wavelength in the specs. wonder if its blu ray as in 405nm or blue dpss; 473?

If you are practical with electronics you can build a 130mw Bluray laser pointer for about $350, just check some laser forums if you don't believe me

I noticed that too...wavelength would be a ***VERY IMPORTANT*** parameter to show on a web page about...a...LASER. :shakehead

Based on the price and the "Blu-Ray" in the title, I'd have to assume direct 405nm. I'd think a handheld 473nm dpss would be more expensive.

Yeah, and that's typical KD.

That thing look exactly like the Optotronis RPL too! I wonder if it's the same body with blueray guts in it.........?

I'd rather purchase a 70+mW Laser Box V3.1 for under 200$.

For the price, its beam diameter and physical construction, I would say it's definitely a cheap Chinese made 473nm portable DPSS laser. I don't think direct injected diodes can produce a beam as fine as 1.2mm, unless if that spec is a typo (never seen or heard one with a beam diameter that thin). And the big heatsink is needed to help dissipate the heat produced from the powerful pump diode due to poor efficiency for LBO crystals (it's a lot worse than KTP). The most powerful commonly available 405nm diodes don't need heatsink that huge. Direct injected laser diodes have fairly low heat dissipation compared to DPSS lasers. I might be wrong on this one but my common sense is saying otherwise .

Cheers.

shameless plug or not, thats a pretty damn good price

So what is the real difference between something like the laser box at 450nm and something like this:

at 473nm, besides the price? What does all that extra money actually get you?

Thanks
