    Really, Really big Dye Laser

    They are not actually that expensive and technology IS my recreation. As you will soon see in the next video, we plan to take this channel forward and cover a much broader range of technologies because both my sons are similarly inclined, even if not "into lasers". The channel may someday...

    Really, Really big Dye Laser

    The next video in this series is now up. https://www.youtube.com/watch?v=TBe0zyv4PvI Hope you enjoy it.

    Really, Really big Dye Laser

    Actually, this is one of the highest energy dye lasers shown ever...period. Please reconsider that. The reason I am posting this video and for that matter all of my videos is not to show off what I have accomplished. I state this wish all through my channel. Sure, I love the support and the...

    Really, Really big Dye Laser

    The next wave will come with Mg ion. Twice the voltage per cell.

    Really, Really big Dye Laser

    Funny you should ask. Another project I am working on is at the other end of the spectrum (so to speak). This is a diode laser pumped....wait for it...dye laser. Who would have thought, but although there has been an enormous amount of work on solid media hosted dyes, the dye degradation...

    Really, Really big Dye Laser

    The limit is peak pumping power. Only a laser driven dye laser is able to produce CW or CCW output. For those that are aware of the single attempt to use high intensity arc pumped dye lasers, the output was so minuscule that it is not worth pursuing. On my Dye laser video "575nm Yellow Dye...

    Really, Really big Dye Laser

    I will be showing the internals in detail in the following videos. The output is 50J...now. I have produced around 100J...once or twice, then the optics fail. I'll show the lens from one of these big shots. That occurred at 12kV charging voltage. The highest output ever generated by a dye...

    Really, Really big Dye Laser

    As I posted on PL, the INPUT power is at 25% (10 kV), but the OUTPUT is far from linear. It is more like 10%. The beam is extremely visible and the duration has no effect on that other than to make it seem brighter rather than dimmer. One microsecond and 10 msec looks identical to the eye and...

    Really, Really big Dye Laser

    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...

    LPF's Presidential Candidate Vote USA

    I find this an interesting dichotomy. As very libertarian in my views (not Libertarian, ie Gary Johnson), I perk up when I hear restricting people's freedoms is sometimes necessary to protect them from themselves. If the government rather than individual choice is the control we set on what a...

    LPF's Presidential Candidate Vote USA

    I can't because that would then be inaccurate. https://en.wikipedia.org/wiki/Hillary_Rodham_senior_thesis And remember,"It takes a Village" ? No ,she is a socialist at heart. Of course, she is willing to take corrupt money and is greedy as hell. This is true of many socialists because...

    LPF's Presidential Candidate Vote USA

    Of course Hillary should not be president. She is an old, socialist carpetbagger who has enriched her family through a corrupt foundation and funding from Saudi Arabia. She would never be granted a security clearance if she wasn't Clinton. Comey made it very clear that she should be facing...

    New Laser Video

    Raman lasers love high peak powers. One of the best materials is actually CVD diamond. It is now quite inexpensive and the only challenge is AR coatings. You can Brewster angle for one wavelength, but not for both. The dyes are easy, just flow them at a high rate. It is the windows that pose...

    New Laser Video

    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...

    LPF's Presidential Candidate Vote USA

    I asked the reader to consider the scenario of the Muslim baker. This was not a rhetorical question, what do you think would have happened? Furthermore, if it had happened would you have learned about it? I doubt it. Also, step back and consider the Muslim problem on a longer time scale and...

    LPF's Presidential Candidate Vote USA

    This might feel good, but it will be effectively a wasted vote. The two major candidates will not be affected by these third party candidates and the decision as to who wins will not be influenced by support for these less popular choices. You are undoubtedly right about the importance of...

    LPF's Presidential Candidate Vote USA

    So, when will the tipping point occur? Thirty years of political correctness and bourgeois concerns about a candidate's hair or her ankles... who will be in the Super Bowel? If I hear about another candle lighting or flag planting or singing around a campfire I'm going to puke. Fox News is...

    LPF's Presidential Candidate Vote USA

    This is probably true, but if he does not run in the end then what matters is whether his supporters will reject Hillary in larger numbers than the Never Trump crowd will reject Trump. The "indite Hillary", rally riots and voter fraud are separate, but not inconsequential issues.

    LPF's Presidential Candidate Vote USA

    Ya, we all got it. You were just trying to make a point and it came out wrong. Don't worry about it. This too, is so true. Both these outsiders have one huge thing in common...they're outsiders. They each attract a lot of support that can go either way. I wish Trump had not, in the end...

    LPF's Presidential Candidate Vote USA

    You have misquoted me. The word "many" is very important and you leave it out. Those who vote for her "ONLY" because she is a woman are bigoted and juvenile. If they have other reasons that "escape me" then they are not voting for her "ONLY" because she is a woman. You think so? It sounds...
