Re: Moving the object to reduce speckle?
The tip of my fiber is not moving, it is the body of the fiber which I am moving in ordert o mix internal modes

Re: Moving the object to reduce speckle?
Greetings I tried something similar and was also surprized by the results: I used a 600µm core multimode glass fiber to mix RGB lasers. One advantage of such a fiber is that it is very easy to couple in the three wavelengths and at the output they are well mixed. One disadvantage is that the output ...

Re: Beam Splitter Problems
If you feed your reference beam into a spatial filter, the simple thin plate beamsplitter may work as the reflected beam would be focused outside the pinhole.

Re: fresh air intake for lab
Thank you for sharing.
So you have air intake and "outtake" in your lab? From what I understand this blows new and warmed air into your lab, and I suppose you have an air extraction somewhere?
Thank you

Re: Bayfol HX polymer
There are some papers out there on shifting the HX200 material. From what I recall it involves using various materials to laminate onto the HX200. One of those articles had a table listing material vs shifting

Re: resent color hologram on bayfol
Can you explain the reason for heating after exposing (I think Zilux requires this but did not know about Bayfol) as well how you use water to mount on glass?
Thanks!
Thanks!

Re: Bayfol
Thanks for this interesting info. What is the point of using UV glue to laminate the film on both sides? I mean, the side with the photopolymer already sticks to the glass plate by itself, right? Is it to have it more permanently afixed? Or is it that using UV resin makes it easier to laminate witho...
