nova and red lasers

[charleytown55il]

simple question. . .

is nova laser ever gong to sell a red laser pen?

 

[LarryQ]

Lots of speculation about that....

Someone here posted an e-mail from nova stating that they were working on offering some new items.

No word as of yet what they will be.

Why don't you drop them an e-mail and ask them.

Let us know if you find out anything!!!

yeah post it up if u find out, i do like red lasers, jsut wish they were more viable, red beams at 5mw would be really cool.

i ordered a <5mW 635nm red on tuesday, hopefully it'll arrive within a couple days, i'll try do a review. everyone says 635nm is a lot brighter than the standard 650-670nm, and quarter to half the brightness of a green depending on who you ask, so i'll be seeing if the beam is even very faintly visible in the dark with no smoke. high powered 635nm would be neat! a 100mW would look like a 25 or 50mW green!

I'd love to see NOVAlasers make a very high powered red laser like 300mw upwards

 

[charleytown55il]

got bad news:

"We are still finalizing our high powered green laser line-up at this time and do not have any immediate plans to carry high powered red laser pointers in the near future. We do, however, work with a partner company Laserglow.com Limited (www.laserglow.com) 416-729-7976. They would be able to answer your inquiry promptly as they offer a much wider laser product selection." (Magdalena)

looks like nova wont have any red laser pens anytime soon. :'(

Only would be worthwhile if it were DPSS - I get the feeling the average laser hobbyist would throw up at the sight of the horrible beam (3-5mm with 3-5mRads?) from a 300mW+ red diode. Problem is DPSS red is so dang expensive

200>mW red diodes inherently bleed red all over!

Very interesting

Can you explain why you say horrible beam for 300+mW red diode.
100-250mW from red diode are the best collimated lasers I've ever had experience with (0.3-0.8mRad). Then again, I'm speaking from limited experience. Why 3-5mRad all of a sudden?
Also, 3-5mm beam diameter is nice imo, and should only help improved collimation.

thanks

The reason is this: A red diode laser specifically designed to output that power at CW will be what is called a "multimode" diode. This means there is not one, but several emitters in the same diode can, giving you the horrible beam specs and divergence that Pseudo is talking about.

aaarrgghh (shot through heart) . . . :'(

you. . you ...dream killer... .you

jk, and thanks for the info Jase. I was not aware of this, although I found it very confusing that Dream lasers spec their 635nm 100-400mW <5mrad divergece. I though it was typo.

Now, question of the day:
Does anyone know how many mW max. are the most powerful 635nm "single mode" diodes ?

Well, if they did, I doubt it would sell very well.
