I just posted a new video on my YouTube channel. This is the culmination of a couple of years of work on a very high energy, 580nm pulsed dye laser. It will be followed, in short order, by several more videos that go deeper into its operation and additional demonstrations of its performance. I...

I just finished installing a DPSS laser that will be used to pump dyes, quantum dots and Raman lasers. The laser is so powerful that we couldn't resist cutting the odd razor blade, potato chip...you know. This is in no way a technical, "how to" video, just a bit of fun. Hope you enjoy it...

Why are all of these laser weapon demos "focused" on CW lasers? https://www.youtube.com/watch?v=gVB2b5Hbm04 I can nearly pull this off myself and if I was willing to use a CO2 laser, I could. This undoubtedly multi-million dollar system has to persist on the target for several seconds. I...

I just completed a new video describing some techniques for constructing your own flash lamps. You can choose to fill them with a variety of gases and at different pressure levels. Because these are flow through tubes, the vacuum requirements are minimal. You can trigger them with an external...

I am still in the middle a big hassle with the purchase of a couple of lasers from China that I discussed in a thread on Photonlexicon. The origin of the problem was with the distributor, but was greatly magnified by the fact that the distributor is also from China. The 12 hour time offset, some...

I wasn't sure if I should post this under the red diode heading because the diode is the red P73. But, this diode is being operated at 608nm in a very unusual set up. Hopefully, anyone interested in either color has a chance to take a look at the video and I welcome any feedback. The...

I'm in the possession of a large flash lamp pumped dye laser set up for use with R-6 dye. The water cooling and dye management loops are separate and remote to the head. Does anyone have any suggestions re. a good in line filter for the 50:50 water/methanol mix with R-6 and COT quencher that...

Drlava is currently out of stock on these drivers and I have a large projector build on hold that needs 8 more Flexmod P3s. Anyone with a lead or able to part with some?

After receiving the Flexmod P3 and finding it perfect for my projector build ie. high current, high voltage and modulation they are now out of stock and the build grinds to a halt for who knows how long. I need 8 more of them. Anyone with a surplus and willing to sell? Or, what else is out...

I recently received some Flexmod P3 drivers and tested both a LOC-815 diode and a Nichia 445 diode. The driver is nicely constructed and works well. Set up is easy. When applying a (+) V to the modulation lead there is a linear increase in current output up to the user defined maximum which...

I received an email notice to a link for a group buy for these sleds, but I can't seem to track this down. It seems like an old post. Nevertheless I am very interested, but maybe just mistaken. Anyone know about this?

Three weeks ago I ordered four Flexmod P3s from a member of PL. I haven't gotten a response yet and my project is on hold. The specs. on the P3 are perfect and I will need 10-12 of them. Are there any choices for sources for this driver or are there any other alternatives to the P3 with...

Planning to run four 445nm diodes in series at approx. 1.2 A from a single Flexmod P3. The test load for setting the driver's current would seem cumbersome if I used something like 18 diodes in series. Is there a good set up for these higher voltages?

Looking on Ebay and through the different forums there seem to be three suppliers of approx. 1 Watt 532nm analog modulation lasers suitable for a projector build. Meierlight, Viasho and CNI. Which is the better choice considering all the usual stuff like price, actual power output...

The far field pattern of a laser diode shows an ellipse/line and it seems the accepted explanation for this is that the source is asymmetrical. The thin aspect of the junction causes that axis to have a higher rate of diffraction. However, while that is surly true, nevertheless the expanding...

I have run some initial experiments with a LPC-815 diode mounted in a heat sink which is in turn cooled by a recirculating chiller. By simultaneously measuring the output and the wavelength at several temperatures, I was able to learn a few things: 1. The wavelength shift with...

I am planning to build a multiple diode 650 nm (4 or 9) lab laser based on a single heat sink with multiple holes to support the can style diodes. I need a good source for the diodes and a glass focusing lens for each diode. I do not need drivers or lens mounts. To make this work the lasers...
