I just find it very interesting. Three days ago you were asking here about Lasersman if they are a good company and now this. So you convinced your cousin before knowing they are any good and before asking here? Don´t tell me they shipped it within 2 days. No doubt. The FireDragons are good...

It´s because the thread where Dino was introducing both sites was deleted as being spam, so all the info there got lost. The reason DinoDirect had to outsurce their laser section was Paypal forcing them to stop selling high powered lasers. You can read here a bit about how it started and how...

LoL. You really have to read a bit more the forum about DinoDirect and their lasers.... But it has nothing to do with the word elite. I even didn´t know they use it in their description but used it to express the FireDragons are the best lasers they are selling. You can buy a FireDragon also...

You will need way more than just a feeling if you are comparing a FireDragon with all the other lasers they are selling. Except you are a Jedi Knight and can feel exactly how much power they are producing. I for myself prefer metering my lasers to know the power rather than trying to feel how...

I secound that. Please keep in mind they are now talking with you BECAUSE you made it public and BECAUSE of the help of such great members here and most BECAUSE they are afraid in loosing their reputation. Without making it public and the help of the others you still would wait for a reaction...

I gave this laser a try. 200mw 532nm Green Focus Handheld Laser Pointer It even dosn´t use a 200mW module but just a 100mW module that was outputing 80mW. Well it was dirtcheap so I replaced the module with a better one.

Lasersman is DinoDirect, just acting under a different name. So the quality is still the same. I recently gave them a try and ordered a 200mW greenie there. The laser I got was just doing 80mW and was shipped in a DinoDirect envelope.

I know but IIRC the very first generation of DPSS lasers had no coatings on the output but on the external OC mirrows and lenses. All the new cristal sets are already sets and coated with mirrows.

Agree on that with you. But am not sure about this: As far I know also the poweful handhelds with a separate diode and cristals are having that awful modedrifting. They also must use optics in between if the diode and the cristals are separated. Therefore I more belive it´s more temperature...

But you are speaking about a lappie, right? In this case the benefit in using optics is obvious. The temperature of the diode has less influence to the temperature of the cristals due to a larger distance, so the temperature of the cristals can be better controlled resulting in a more stable...

I´m interested in his results too, but I doubt proper optics on the pump side can improve the efficiency. I´ve played a lot with IR diodes and cristals in the recent past and tried different setups to imprive the efficiency, but always got the best results by having the diode as close as...

Let me guess. The collimating 3 element lens is designed to exactly catch the wider edges of the beam at its edges. By using a expanding lens the whole beam is streched more so the wider edges hit the housing of the 3 element lens and the narrower edges are closer to the glas edges. So you got...

You are welcome :) :beer:

The cristals look interesting but also to have less efficiency than the ones used in the 400 to 500mW handhelds. So compared to a handheld you can get for less than $200 the cristals are a bit overpriced. Plus they are also wanting $14 for shipping for such a small cristal. :eek:

Here it is: In the middle the golden looking brass module surrounded by the silver looking aluminium ring that is pressfitted into the housing.

You don´t have to knock on the module but the piece of metal that is touching the aluminiumring. You can also add a drop of oil between the ring and the host so it will be easier to get it out. So if you will do it carefully and take your time, the whole procedure will be quite safe. The...

Re: Problems with lazerer This time I also didn´t recive the mails so checked the status by logging in. Max had some problems with his shop system on his server, so maybe the mails are not send anymore due to some changes. There is still nothing to worry about. Now before christmas i may take...

Re: Problems with lazerer When I ordered my 400mW greenie at lazerer the company was still totally new and Max had a lot of time to write with me. After I ordered my Laser it was shipped the next day and arrived 10 day later. This was while Max started his bussines. Now Max is a quite busy...

The head is just a piece of aluminium but the module sits in a aluminium ring that is pressfitted into the buttom of the host. I have a very simmilar host where I replaced the module with a 220mW one. First you have to remove the foam sitting on the spring. Then you can see the driver behind...

You have to knock out the aluminiumring where the brass module is fitted out of the housing.
