    ebay seller cables-n-peripherals Lightwave Halfnote

    Hello, wow its been a long time since I stopped by. Been away from lasers for a while. I just wanted to quickly let everyone know about a bad experience I just had with an ebay seller called "cables-n-peripherals". I won an auction for a lighwave electronics Halfnote 2.5w 532nm laser head but...

    Project Enclosures (Free Samples)

    They have not called me yet and it has been over a week.  I don't mind if they do.   I plan to purchase more project enclosures from them in the future.  So hopefully it will be a win-win for both Pac Tec, and me.

    Project Enclosures (Free Samples)

    I just got a couple of free project enclosures that are really nice.  They came from Pac Tec as free samples.  Here's the link to them. http://www.pactecenclosures.com/New-Enclosure-Products.html They will send you up to two free samples of their new products (cases), no charge for shipping or...

    Consumer Alert - 5mw green may really be 50mW

    This is where I got mine but it has been several months ago.  Price is now only $11.99.  I should have listed this from the beginning.   http://www.dealextreme.com/details.dx/sku.91

    New Star Laser 200mW Green Labby

    Don't know what you had in mind, but here's a short video of the beam spot on a flat black surface at 20" from aperture. NOTE: the secondary smaller spot is a reflection of the primary spot off the camera lens. What's cool (to me anyway) is that it's slowly burning the black poster board and...

    New Star Laser 200mW Green Labby

    I recently had the opportunity to check out a Lab style laser made by New Star Laser Technology: http://www.newstarlaser.com/product.htm email: jane_newstarlaser@hotmail.com and thought I would pass along what I learned about it, in appreciation for all the help I received from the...

    I guess I'm behind the times. You know what they say about assuming :-[

    Consumer Alert - 5mw green may really be 50mW

    No, I don't think they would care either, in fact I wonder if they are doing it intentionally in an attempt to regain some sales they recently lost by not being able to ship anything >5mW to the US (hint). As in "maybe, we'll sell thousands of these when word gets around that they are really...

    Consumer Alert - 5mw green may really be 50mW

    I recently ordered one of the very popular, cheap, 5 mW green laser pointers and noticed it was very, very bright for 5mW and I could see the beam in the daylight. So I checked it with my LaserBee and it was putting out 50mW :o I then put a NOVA IR filter between it and the thermopile and the...

    What is up with this beam?

    Thanks FrothyChimp. That really helps put things in perspective. It isn't a top end laser and the beam quality was supposed to be <2. It has great power and stability. I'm probably looking for perfection where perfection should not be expected (I tend to do that sometimes) Oh, and after looking...

    What is this?

    That's what prompted me to test mine, it was very, very bright for just 5mW. Another way I recently did some infrared testing was by using a little red filter that came with my mag light (used to make the flashlight red). I found that I could not see green through it. Put it in front of the...

    What is this?

    Way more than 5mW I just tested one of the sku. 91 from DX. LaserBee power meter indicates that it is outputting 50mW. Yes I typed 50 :o. I then put a nova IR filter between it and the thermopile sensor and the output dropped to 36mW. Allowing as much as 6% visible light drop for the filter...

    What is up with this beam?

    Here's a photo of the aperture. This is looks to be pretty sloppy work but I thought maybe it was ok since the beam appears to pass through only about the center 3-4 mm of the lens. At least that's about the size of the spot I can see a reflection of on the lens. There are also several specs...

    What is up with this beam?

    I just took this with a different mag glass. It is expanded to about 8 inches in this shot. The laser is a LAB style with TEC & T03 style pump diode, running stable at 245mW(+/- 1mw). The beam diameter at the aperture is ~3-4mm and the divergence seems to be about 1.0mRad. Yes, there is...

    What is up with this beam?

    Oddly enough: This is about the best I can do with mag glass. I must be doing something wrong.

    What is up with this beam?

    For whatever it may matter: this is a 200mW lab style with TEC cooling.

    What is up with this beam?

    If I understand the definition of mode shifting, it is not. The mode, whatever it is, stays that way. even if I vary the power the spot still looks the same, etc. My thermal image looks like the TEM01* from the Laguerre-gaussian chart in the Wiki article (assuming the white part on that chart...
