Default 50mW 473nm DPSS

Hey all, a friend found this on ebay and was wondering whether this is a good deal or not. The video shows that it peaks and averages at 116 mW and 110mW respectively. Here are the links

What do you think, is this worth buying?

At first sight it not seems wrong, but you can also consider these other.

Here you have the same, but cheaper

50mW 473nm DPSS Lasers :: DPSS Blue Lasers :: Ultralasers, Inc

And this other possibility

50mW 473nm DPSS Blue laser/laser alignment/ blue laser pointer products, buy 50mW 473nm DPSS Blue laser/laser alignment/ blue laser pointer products from alibaba.com

The Second one is <50mW not big deal.

but <390$ (plus shipping) for >100mW 473nm it's a Good deal.

Maybe i will take this Non-Functioning 473 nm Blue Laser, DPSS, BWB-10-OEM - eBay (item 320695582008 end time Jul-05-11 17:07:04 PDT)

10mW used (2004) for 35$!

Considering that the wavelength is similar to 445, you could just get one of the A140's that are floating around. They are much more powerful too. But they arent that wavelength nor are DPSS

I would choose a 473 over a 445 any day and colorwise the 473 is a tad more cyan colored and ofcourse the beam owns a 445 by far

What you said. I have a few 445 lasers around. Never seen 473 though :/

Always opt for analog modulation. TTL kinda sucks.

Newbie question: Why do the majority of 473's I see seem to be installed in a Lab-laser configuration? And I frequently hear fans in the videos...

Do 473s run "hotter" than others, or do they need higher-current drivers or something?

A related newbie observation / question: I'm interested in duty cycle/cooling. I WAS assuming (at first) that heatsinking was mainly for the diode/DPSS, but when it's mentioned in DIY threads, they almost always reference cooling THE DRIVER.

DPSS 473nm is ridiculously inefficient. Watts of optical input give you only a handful of milliwatts of optical output. This probably has the same cooling requirements as a 500mW 532nm system.

Trevor... and so the inefficiency translates to waste heat... (and you need to shove a lot of juice at it to get it to do anything) ... got it, and THANKS for edumacating me.

Default Re: 50mW 473nm DPSS

The rise of the 445nm diode has sure driven he price of 473nm, DPSS units down

473nm is a very cool color. I would recommend that any "serious" hobbyist should have one. However, I am not sure that the price has hit bottom yet

Peace,
dave

Daguin - yes... If I could have just ONE laser, it would be Cyan (tech problems aside). I suspect it will be quite a while B4 I own one, though. Who knows, MAYBE there will be a technical breakthrough sometime.

Don't forget you're talking to the man with the argon lasers...
