i wonder if we could obtain high power module from the 5 mw one. There is the same diode inside them, the same crystal with are bonded together. The same current. The only difference , i guess, is in the direction of polarisation of pump diode with the Nd:YVO4. By carrefully unscrewing the...

Here is the graph from Mike for the Stenkat 808nm 200mW diode "I ran this diode later at 400 mA (270 mW) for a life test." I made some research about the optical conversion efficiency of 808@1064 with Nd:YVO4 and 1064@532 with KTP. These conversion efficiency can drop dramatically if the...

hey ! nice picture ! you got them from ebay ? i have 5 of them, they are really nice!

just send a little contribution; i learnt a lot from this forum which become more and more bright as time pass; thanks for time preserving this forum !

hi =) for the lifter, check this page http://jnaudin.free.fr/lifters/main.htm The secret is to build very lightweight device with balsa wood, mine weight no more than 4g.

the current of diode pump on o-like module is nearly 350/400 mA ? so it's well aligned. Otherwise i have a 5mw version and the output is decreasing, i suspect overheating of module (cold it work again) So are the 100mw+ from olike stable without heatsinking ?

there is only one manufacturer of tritium light, check his site : www.mbmicrotec.com the one of my picture are 1.55 mm diameter and 2.2 cm long, green is the brightest, but blue and orange have nearly the same brightness as green mmmhhh so i guess that price... are not as good as i thought (on...

i can assure you that these thing are great, in dark room, they produce quite a bright light (but won't light your entire room) they are terrific as "key holder" in night here is my little contribution with my poor picture taken with a 7 year old camera they are MUCH brighter in reality =)...

Dang! your avatar is freaking me ! i hate spider =)) bye !

mmmmmh is the beam spec of a 9mm diode similar to a 5.6 mm diode ? only one lens could produce a nice beam?

i wanted to do a search about 9mm diode but i can't : when i type "9mm or 9 mm" it's telling that it's can't do the search coz "The following words are either very common, too long, or too short and were not included in your search : 9mm " mhhhhh so i can't access to thread which talk about 9 mm...

Hello ! I saw your auction on ebid, very interesting price ! (more than here =) ) "HIGH POWER IR 808nm 2W DPSS PUMP LASER DIODE LOT of 2 for 35 $ 9mm diode it might be an error ?? the price is very low when i saw price's cmount. otherwise, it produce a beam that is almost the same as c mount...

i dropped a message to him this morning through ebay response : yep, he's a bit angry towards Chris ! sad story IMO.

Can you tell more about the optic to focalize (to infinite ?) your cmount ? you used the one from the mounting design and place them into a pen ? how much do you pay for your CNI c mounted ? :)

Going to supply with 2 ips power supply which can pump up to 40 A (but the problem is that 5V maybe very light for the lm317, planning to use 2 power supply to have 10V) here...

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP Hum, i have another idea !  :D What about that from o-like ? http://www.o-like.com/b2b_cpinfo.asp?id=923 If it's cmount, and optic not really coated, im sure that we can exchange the cmount 808 into a red one to have a good beam... Terrific...

Really ? ;D ;D ;D Interesting review ;) , im impressed about the power of the 808 nm and 532; do you buy it at o-like.com ? i can't find it (the 808 nm one) :)

Dunno if im telling shit, but im planning to build a 40 Amp regulated power supply with 50 lm317 (yes, i didn't studied the power of mosfet befor buying my 50 regulator). So 2 lm317 can supply 2x current if added in parralel :

Re: KTP Crystal- for changing from 808nm (IR) to 5 u mean 532 ;) ps/2*2*5mm KTP cost no more than 40 $usd

Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP i got my package this morning and i must say that im very happy, thanks chris you Rox !  ;) Some picture of my day-mod : First, you can see some parts from chris; the Tec driven at 6V need almost 3.3A and a massive cooling. A note on indium...
