I'm not sure if the gimbal mounts will provide me with any more adjustment that I don't already have. Though the XYZ positioner has me interested. Pending your price. However, that being said, a 4-axis 1" positioner from Thorlabs is $220. 6-axis for $245. So you'll have to convince me on...

:wave::wave:Hello all!:wave::wave: I have recently-ish changed my medium of research from gas/ion, to solid state. More specifically, diode-pumped solid state. My one main setback is decent quality mounts made for DPSS. I have plenty of decent mounts that cover coarse X/Y adjustment. I've...

Re: Possible cheap 2-line 980nm/490nm pen Well this escalated. I'll grab a couple cheap pens off eBay. Considering a 1W diode or something like that too. As for doubling the 980nm using Yb fiber. Getting the Yb fiber will be the easy part. And that's saying something...

KVANT sells 100mW 607nm for $2900. I own a composite crystal. Yeah, drop it in front of 808nm and you're set. Now I'm doing a "real" linear cavity. Anyway, I'm off for the night. I'll send you my skype if you ever use it.

Possible maybe. Far-fetched? Absolutely!!! For DPSS, I am currently messing with 532 to get my feet wet. Just to learn how the optics behave, how the cavity behaves under certain conditions, etc. Just learning the basics right now. I currently have a diode (~1-1.5W) w/ TEC. TEC in...

Still doing lasers of course. Just a new medium that I can start fresh with without breaking the bank. I was thinking of the same thing a little bit ago. Using a design to an optical chopper, but have 90% of the wheel be a parabolic mirror. The trick is balancing the mirror coverage to dump...

Erm.. Everything about everything? I'd say advanced. I've held my own in a university lab, as long as they keep the equations out of the topic. Gas is the one realm that I can really talk for days, though I am by far nowhere near "expert". Hell ... I almost feel boastful claiming...

Oh don't get me wrong, as do I. While I was at SELEM, I snagged 5 optics for $20. 2 CVL HR's, one for 578, and the other for 511 (I could tell by the tint it gave the overhead light's reflection). The other 3 were CVL OC windows. I grabbed them as I knew it will happen someday. Though a...

I did not. If I am ever presented with the opportunity to play with a B-Tube, I likely will, though. However, my current interests are starting to sway towards solid state. As I think about that, I am almost .. saddened. It was not long ago when my only desire in the world was to grab a 1-B...

I've yet to see a "Cubote" ad. Just the usual Toplasers ads. Also, the one Sci-Fi laser ad as well.

First one is a high reflector @ 45 degrees. So I guess it could be useful in a ring cavity, or an L/Z-Fold. Like a bounce mirror I guess. Though not useful for a linear cavity. That being said, all 488nm DPSS is done via direct-doubling. So the only possible use is via a ring, or possibly...

Re: Possible cheap 2-line 980nm/490nm pen Is that some kind of joke?

The entire diameter of the GLP is only 16.5mm. The case is likely only about 1-2mm thick. So the module may still be the same 12mm module, or not far from it. Also. Side question. Can you ask about their 808nm labbies? Specifically: MDL-H-808 -- 2W, 4W, and 6W MDL-808(FC) -- 2.5W, 5W...

The Firefly4000 is a CNI brand spectrometer. I am also interested in a price for this. compact spectrometer-firefly4000

How did I know Kaiser would beat me to this ... ;) I surely do hope the reagssing goes well. Though as mentioned, there is a reason these cost so much. Also, there's another very valid reason for why a 632nm tube 24" long may get upwards of 12-15mW, whereas a 612nm tube of the same length...

Re: OPEN: ROUND 5!: THE "Skylaser" (laserBtB) groupbuy! Is there a way to get the 20mW 515nm pen? It's normally $68, which is around what some of the other cheap lasers in this GB cost. I just have a weird OCD with putting weak diodes in big hosts. I like small SM diodes being in pens...

Hello :) I think I've made a couple similar threads. Though before I was looking into making an investment that really never took place. Just wasn't worth the $300+ investment cost. I am looking for something simple. A good camera for around $100, that I can alter the shutter speed on for...

Bout to buy. What else do I need besides to the camera to get up and running with this guy? Pardon the noobness. Also, will I be able to take time-lapse photos? I.E. alter the shutter speed for beamshots with my low output HeNes and other gas units?

Fun Fact: In the previous fun fact's contained gif, all the red shirts pulsed due to wicked cool science reasons. Fun fact: Fluid temp has no effect on rate of hydration. According to baby science.

What other 561 pens?? ;)
