Fiber Guide

[Roger O]

Hi everyone, I know that this question may have been asked before, but with no real answer, or solution. Does anyone have the ability to help me build a 445nm high power (>3 watt) lab laser that will fire into a fiber optic light guide?

Fiber will be about 600u in diameter, and made of glass, with a length of about 6' max.

I realize that I will need various optics to collimate and focus the beam, but I am not knowledgeable enough to know what is needed.

Thanks for all your help and cooperation with my project!

P.S. Please feel free to PM me.

We can help you a lot better if you actually tell us what your project is.

The project is using the output for studying various optical effects of the blue laser. I wanted to launch the laser into a fiber optic guide because it is easier to use the fiber light guide for local close aiming at many different samples quickly (usually perpendicular to the laser) as opposed to either moving the laser itself (tedious and not consistent), or by mirrors as is done in an laser optics lab.

Although not a laser engineer per say, I have a fairly long background (since 1992) using high power lasers of various wavelengths. The lasers I have used for the most part have been commercially made, and this is only the third homemade laser I am making, and the first with an optical fiber guide, if it can be fairly easily done.
