    Hello, I have all of the the mirrors and optics on their mounts, Q-switches and YVO4 mounts with crystals from a Spectrum Physics 1064 nm HIPPO laser head and trying to understand the beam path, not quite getting how they combine the two beams together. Does anyone have experience with these or...

    I've done that before to characterize hologram optical elements for diffraction efficiency vs. angle. Fixed input beam, HOE mounted on axis of a motor-driven rotation stage, arm with detector mounted on another motor-driven rotation stage (both axis' of rotation collinear), with the detector stage...

    Thanks. Not chasing shg on this setup. Its sum difference. But most of that applies. I will check it out today and it think your right on the interferometer. That could be half the problem.

    If you were just doing SHG, a Fresnel Biprism is the magic constant deviation prism optic with a beam crossover at a nearly constant point. . I've used them in a focusing interferometer to shoot gratings for the Air Force on a project using a Liquid Crystal material. One Biprism made the whole...

    Last time I looked at that problem while at Cee where are you, Professor Sierra was not telling me what signal I was looking for or what the polarizations should be. One target was the sample, which was to be behind a IR capable window and 40 uM of DI H2O for the 'lectrochemmisery. So I just...

    It would be incredibly useful if there was a way to just check a box that would force the output to be one complete cycle. I understand that the color cycle is not resolved yet but in this use case the easiest thing to do would just be too always output one complete cycle. That means that the...

    Are there specific plots that you are having trouble with? Only plots that employ rotation are loopable for now. Color schemes do not loop, so you may see a large color change at the rollover point. The default rotation rates are in hundredths of revs/sec, so the overall cycle time should be...

    I'd have to check the limit but I know the ILDA standard maxes out the possible number of frames at a 16bit number... Either 32768 or 65536 depending on whether it is signed. I think software could ignore and play whatever is in the file but that would be non-standard behavior.

    Steve this is the picosecond sum difference experiment. Im looking to shrink it down and path fold the delay line. Taking the topas out with the tsunami out. Need to path length Mach then overlap precisely on a sample to form a difference and summsignal. Aligning is insane so I want to make...

    I believe your optic is a F1 lens on a translation stage and a couple of mirrors or prisms to feed two beams in, equidistance from the center of the lens. The whole lens and mirror set must move in unison. Its worked for me for doing LDV. ...

    Ok I feel stupid asking this but you never know. Is there an optic that can take in a beam at an arbitrary angle and output it to a set other angle? I actually need to do this in reverse. Get a beam in at a fixed angle and then rotate it to some other angle. Sure a mirror but how to keep a...

    Perhaps it was 32775, I was guessing at some numbers I saw over the weekend. It must be a bug that the tool allows for the import of up to 100,000 frames if the timeline can only support 32775.

    I haven't used the utility, but I've imported large ILDA exports (exported by Mamba III). LSX's frame catalog is limited to 32775 frames so I'm surprised that you made it further than that. On a side note, older versions of LSX had issues saving really large show files reliably, but that got...

    ANyone using this function in LSX have you had success with any shows longer than 30 minutes. It works perfect for about 10 mins or less but every time I try a full show, it states it will be near 90,000 frames, then when it gets done there are only about 38,000 frames created and some of the en...
