i bought this recently at focal price for 13.92$. Focal price link First the internal picture : Note the giant heatsink used for the crystal : almost twice as O-like module or other common greenie. The module is easily unscrewable. The picture above show how the green module is put in...

Hello ! a rapid thread showing an homemade DPSS system : ORIGINAL PICTURE of the discovery are IN THIS THREAD : http://laserpointerforums.com/f52/o-like-crystal-40671-2.html First you need to know a little about the working of a green dpss, this picture come from sam laser FAQ : In the...

There is one picture showing dpss but i didn't remenber who take it, this picture lies somewhere in the forum : Here is my contribution of diode pumped solid state laser. Picture are not photoshoped (just resized), taken with a panasonic fz28 +water fog to reveal the beams (you can notice...

Hello all, some picture of my relatively "poor" laser made in hurry. I made some labby style unit thanks to sightfx heatsink, which are well made ! the specification are below the picture. Next, im gonna build my DIY 532 nm from Susie's crystal and some FAP800 unit ! ok i admit there...

I'm wondering what's the limit in current of a long open can red diode. I made an experiment today, which was an epic error. I made a labby style Red diode feeds at 505mA , and massively heatsinked. I also have my ancient mxdl built which contain the same diode at exactly 460 mA. When i switched...

As the title say ! im interested in some 300mw 5.6 mm too (very rare); i would like to know if you have a good source of these at a relatively fair price i need them to repair some greenie thanks for all proposal

A tiny review about Susie's Crystal : http://www.o-like.com/b2b_cplist.asp?catid=467 i bought the "High end Optical Crystal GKTP " one and the "Laser Crystal YVO4-331 (applied to <300mW)" They were well packaged as usual and fast shipped In the picture, a typical KTP and Nd:YVO4 crystal...

Hello ! i would like to share with you some picture with glow in the dark powder from http://www.readysetglo.com/Oil_based_Glowpowder.asp First, you have to know that the market are oversatured with glow in the dark Paint/Powder seller, i choose this one because i wanted to see with some...

I recently found accidentally that Susie sell KTP and YVO4 crystal at a fairly good price ! http://www.o-like.com/b2b_cplist.asp?catid=467 Dimensions for YVO4 is YVO4<300mW   3*3*1mm   Nd percent @ 2%      30$ YVO4>300mW   3*3*2mm   Nd percent @ 1%      48$                 +4$ shipping also...

I post the same thread on "deal section", i post here a fast review of this great seller : Hello people  ;) I would like to share with you some interesting stuff such as non equilateral prism that allow you to make double total internal reflection, so the laser beam is send back to the emmiter...

Hello people  ;) I would like to share with you some interesting stuff such as non equilateral prism that allow you to make double total internal reflection, so the laser beam is send back to the emmiter ... there are many other application, for example to play with some light path, or also...

Heya ! I did a research on this forum and can't find the word "ulexite" so i put here my experiment of this day : From wikipedia : "Ulexite (NaCaB5O9·8H2O) (hydrated sodium calcium borate hydroxide) is a mineral occurring in silky white rounded crystalline masses or in parallel fibers...

hello forums  ;) I decided to push a little the concept of "double laser" , in adding a green laser. I didn't have a working unit of green, so i build it with a Stenkats'Ir diode . I had a huge amount of problem (i fried 2 Ir diode), and was obliged to fill off some of the screwing of the MXDL...

Hello all !  ;) Here is a new MXDL project with a 803T which can be set at 125 ma (default current) and at 173 ma, through a miniature switch (found anywhere) I added a switch to play with 2 value of current instead of set the diode directly at 173 ma, beacause i remenbered one phrase from IgorT...

Hello all !  ;) I fried my 50 mw newish type when i was trying to high the current flowing to the diode  with a ddl driver . So i bought some Stenkat's Ir diode to replace the fried diode ( which worked at 400ma). To dismantle the laser, see...

Hello forums ;) ! One of my friend wanted a laser, so i decided to build a new one using the same host but with 2 module inside it : A PHR-803T set at 125 ma trought a Rckstr's driver and a Stenkat's diode 1239JL-54 at 348 mA (for specification of these diodes see...

Meta Topic : Pinout & Performance of actual LD Hello all ! :yh: Here is a topic which collect all the usefull information on this forum in order to spare time ! i Ctrl-c most of the topic of members, hope there is no copyright :thinking: To move right/left on image, left clik on the image then...

Hello all !  :D it was approx 2 month ago that i found this amazing forum and that's how i decided to make some experiment with laser diode. Here is some picture of my last laser : First, at the beginning i bought a red module on DX But i was a noob and i connect the red pin to the green pin...

Hello all  :D With 2 different powermeters at faculty ($$$), we obtain these result , for a PHR 803T from psxboy , using a mc33269 (ddl style driver), 11 ohm (111 ma) and 8.3 ohm (147/150 ma) resistor and DX acrylic cut lens, no focalisation: 147 ma  =>>  105-110 mw 111 ma  =>>  60-65 mw Im...

Hello !! (from France). This forum is full of excellent idea and ressource, its an honour to be here  :) I have a question, or remark :D DDL driver need at last 6V to be full operational, that 's why we need 2x 3V CR123 battery with a mxdl Host. To higher voltage just add few 1n4001 in serie in...
