Hali Halo, Ich can nicht deutche gute sprechen so I will take this in english. I have been away for some while now and I hope I don´t offend anyone by speaking english. I live in sweden and I have a huge interest in lasers. Few years ago I bought a popelscan system from Guido. (is he stil around?). ...

I have a lasershow to do in one day and i need that small program that allows popelscan to work on win 2000 pro.. that port thing you know? Where can i download it?

Hi everyone, As I wrote in my last post about ending my journey into the DPSS world I want to explain the reason. I have a business on the side of my original work that will eventually give me time an financial freedom to do the things I love doing, LASERS!! However it will take me some time to reac...

---Guido: Hi there <img src="/images/graemlins/smile.gif" alt="" />, Thanx for the info. I checked the specifications for a 250mW 808nm. They did not have a 200mW. The numbers are very correct. The threshold it say is about 160mA to 200mA. If you look at my pictures I got my first lease at 171mA. An...

My very first working DPSSL!! It looks like some creation by Frankenstein but it works and I am working on improving the construction! I will use it for a show tomorrow, does anybody know what max current I can use for a 200mW 808nm LD?? Check these pictures out! http://focus27.tripod.com/dpsslaser/...

You have to copy and paste the adress otherwise it does not work for some reason.

The party went great! The people really like the show, and pictures were all out of focus becouse of the smoke from the smokemachine. But I will work on that and send some pictures anyways.. A question, when I run my homemade DPSS through a composit crystal (have not tried yet ro tun it yet the norm...

THE POWERSUPPLY IS ON ITS WAY!! I should recieve the PS today as I tracked it on TNT´s page. I have a party coming up the 28/6, so my DPSS will look great with some smoke from the smoke mashine, a 15mW HeNe, a 150mW Argon and Guidos system which I tried out yesterday. My room looked like it came fro...

I got my DPSS working yesterday night!! It was the batteries, they were old and thats why it would not work the night before. I took my composite crystal http://focus27.tripod.com/dpsslaser/crystals/crystal1.html and just placed it next to the diode. After some turning of the crystal I got some gree...

I was just curious if it would work. Yesterday I got a 808nm 200mW LD from the company I was in contact with. I connected the LD to 3 1.5 volt batteries (4.5 volt) with 170mA. I saw the IR ligh come out so I understood it was working. I took one of my crystals (the composit) and put it in front of i...

Hi Hatschi,
Sorry about the misstake, lets try again.
I meant the microscopic chip like Indium/Gallium doped Arsenide. Would it be possible to replace that with a chip producing 808nm??
Marcin

Hi Harald, I will order that powersupply today. Even if it only has one TEC its pretty good for that money right? I have had some thoughts recently. Would it be possible to take a simple 5mW 650nm laser diode and replace the crystal with an 500mW 808nm crystal? I have done some surgery on a simple 1...

Ok, This is the powersypply I will by. TEC included! 90$!!! Can it get better than this?

Tracky: Have you seen crystals like that before? Do you think I could get at least 100mW from it? Can you se from the pictures if it will need an OC?

Here are some pictures of the crystal I found in the other module. I could not find an Output Coupler (OC) in the module, and I could not find a Nd:YVO4. Could this be a comosit..??
http://focus27.tripod.com/dpsslaser/cry ... stal1.html

Yes they are different. http://focus27.tripod.com/dpsslaser/module.jpg is different from http://focus27.tripod.com/dpsslaser/ktp2.jpg I think that http://focus27.tripod.com/dpsslaser/ktp2.jpg is a composit crystal. When I opened the module I coud not find the Nd:YVO4, I only found that on the pictur...

Hi Hatschi,
What do you mean? Have I given some wrong info??

The links should work now. But you still have to copy and paste the adress!

Hello,
I dont know german so I will write this in English.
Would mobilephone vibrators work? are they fast enough? Has anyone here tried them out?
Marcin

Ok, I am almost finished dissecting the two modules. They were glued together and it took some time to do the job. One of the modules when I opened it did not have only had the KTP, I could not find the Nd-Yag. Could it be a composit??? Maybe I just lost it?? Here is the picture of the crystal it se...

I have been to the meeting and I have positive and negative news. Negative- He only had two broken DPSS modules, I got them both for free (will use them to learn more about dpss and build my first one!!). I think there could be a way for him to collect broken modules from different places since he h...

Hi There, I have found a company here in stockholm which sells laser diodes and modules upp to 4W!. I have a meeting today to se how they work and get a good contact with them. I have asked them for broken DPSS laser modules and they have plenty, if I get lucky I can by some for a lower price. I don...

Hi Hatschi! I have looked at Andi´s ND:YVo4 that does not need a OC. I think I will still go for the offer I got from Lasever. My economy right now is not to exciting and I am also buying some hardware from Guido. Can you tell me if there anythinhg else I need except for these parts that Lasever has...

Hi there I think I could build an airtight seal and cover for it, if that is the only thing that the mount is for or that the diode must have. If you have any ideas on how to build it you can tell me. I have started with the mechanical parts yesterday and I will put some pictures out today on my fir...

This is the diode they are selling. The diode is C-mount in TO3 package. Why would this not be a good start?

Hi Hatschi I have sent an email to Lasever and asked them about the mount. Should recieve an asnwer today. So you want to buy that powersypply, good <img src="/images/graemlins/wink.gif" alt="" /> then I can use you as an experimental rabbit..hehe, just kidding. Let me know when you get it. I want t...

Hi Hatschi So you say its a good deal huh? Thats right, they say its a 1W module. Perhaps they dont really know what they are talking about? How much power do you say I could get out of this thing? When you say combined crystal, do you mean the hybrid or composite crystals like the CASIX DPM (DPM010...

This is the specifications I got from the company regarding the crystals.
The size of KTP is 2x2x5mm.
The size of Nd:YVO4 is 3x3x1.
Nd:YVO4 is 3%
doped.

This is the powersuply they are offering
http://www.lasever.com/LSR-PS-II.htm
I found out that it is a 1W diode.
Question. Can I get more than just 30mW with this Power suply and 1W diode?

Hi everyone, again. Seems like I am the only one putting out posts out here. Like I said I want to build a DPSS. I wrote an email to this company called Lasever, anyone heard of them? And asked for a complete 30mW laser or a kit. These are the prices I recieved. Complete 30mW DPSS 532nm--------450$ ...

Hatschi has given me some ideas and I am convinced now to build my own DPSS laser. I think I have read just about everything I could get hold on about these on Sam´s hompage. I am still in search for an Argon though, but totally convinced to build a DPSS!! Cant wait to get this project started. Wish...

Thanx for the reply. I checked out that page, still a litle too expensive for me. I have popelscan at home, I am waiting for the hardware from Guido. Do you have it? Does it work well?
Marcin

Hi! I have recently taken an interst in my lasers again. I have about 14 HeNe and i am about to buy Popelscan v 1.9 (laser scaning program) from Guido. He Has his own forum here. I am a litle tired of my HeNe and I want to get an Argon now. I have tried with xerox and asked them for their old indust...
