NEW !! Green Laserdiode

[Arni]

Look at this link, there have green laserdiodes. Green

 

[LaserMod]

I'll just add a more direct link: /ubbthreads/images/graemlins/smile.gif

http://www.sp3plus.co.uk/green-diode-lasers.htm

I'm not too convinced...are they not diodes integrating the crystals into the one unit? /ubbthreads/images/graemlins/confused.gif

If they have finally been invented that means:

~no more stability problems.
~expensive at first but the cost will drop quickly.
~no more dangerous IR.
~much better battery life.
~no more effiency/conversion factors.
~no more delicate crystal sets.

We need clarification... /ubbthreads/images/graemlins/popcorn.gif

 

[paulr]

They are DPSS which means the doubling crystal setup.

 

[comozo]

Now , if they were direct injection green diodes, that would be something.I don't see anything to get excited about.

 

[LaserMod]

Where does it say DPSS, I didn't see that...

 

[LaserMod]

The link keeps defaulting to the main page...here's an extract from it...click 'Products' then 'Green Diode Lasers' I see no mention of DPSS or MCA sets.

"GDL 6000 & 7000 Series

The key benefit of GDL is the Mini-size with standard LD package. It is the smallest 532nm laser in the world with standard 9mm TO package. It could be easily installed within a system to replace a red laser diode. Another key benefit is its low-cost . The design makes it ideal for the replacement of traditional red laser diodes which have only 1/5 of the brightness compared of a green diode laser.

The Green Diode Laser can be used with an optical collimator and 3VDC. The laser should be mounted with a heat-sink - DO NOT OPERATE THE LASER WITHOUT A HEAT SINK MOUNT.

Applications Include Features Include
Laser Module Low cost
Laser Alignment & Pointing 532nm Output CW
Crystal Inspections TEMoo
Laser Scanning Easy Operation and Free Maintenance
Build - in Laser System It is the smallest 532nm laser in the world"

 

[Raccoon]

Seems someone here needs to buy one and play with it.

 

[bg2vo]

It must be DPSS with build-in crystal. One line from the specs says 'Residual IR'.

 

[LaserMod]

Possibly... it does have a larger depth than a standard diode.

How much do they cost?

 

[Arni]

I have sent them yesterday a email and ask there for the price. they haven't send any answer until now.

 

[Arni]

I have received the prices.
Here are the Pricelist:
Green Diode Laser Price List
Description Quantity Unit price £ each
GDL-6001 1~9 £53.30
10~99 £47.00
GDL-7001 1~9 £59.70
10~99 £50.30
GDL-7020 1~9 £125.70
10~99 £94.30
GDL-7050 1~9 £187.00
10~99 £144.80

currency course:
1.00 GBP
United Kingdom Pounds = 1.88740 USD
United States Dollars
1 GBP = 1.88740 USD 1 USD = 0.529828 GBP
and in Euro: the 50mWatt diode costs about 271,- €

 

[PhotonWrangler]

If this is truly an integrated DPSS unit, it's a novel idea.
However if you drop it and the crystals get out of alignment, you can't disassemble it to realign them.

 

[Wyvern]

also if it is dpss then maybe they are moddable to well over those specs? possibly?

 

[LaserMod]

Yeah and unlike the Leadlight assemblies these will be more stable and less complicated as the largest is designed for 50mw @ 750ma. The heat will be a problem though... /ubbthreads/images/graemlins/icon23.gif

 

[Wyvern]

unless somone makes a mini tec which fits in a laser pen and runs off 2xAAA batteries it will be no use at that power
although how much do you reckon you could get out of it strapped to a 120W tec with a big heatsink

 

[Guliver]

Yep..Look at the specs ...DPSS
second set of specs (user manual) shows it
According to a friend who seen these at a show a few weeks ago say's they are DPSS
Pretty Nice tho /ubbthreads/images/graemlins/grinser2.gif
Here's a link to the manufacturer

[comozo]

From alt.lasers.
"Those are just 808nm laser diodes with a Casix DPM mounted in front.
Photop had them on display at Photonics West a few weeks ago and has a
bit more info on their web site" Which Marconi provided

 

[LaserMod]

Thanks Marconi, but with a Casix crystal set - thats gotta be good. /ubbthreads/images/graemlins/smile.gif

 

[Bengal]

Interesting, they have a schematic (pot mod!) and 50mw+ models
Prob cost an arm and a leg though
