Default SFG experiment

Has anyone ever tried PBSing a two individual beams like 1046+1319 and then putting that beam thorough a NLO. Through all the scientific experiments I've read I have never heard it done this way. I know that he beams would eventually come out of alignment but it would be interesting to see its effects on efficiency.

Default Re: SFG experiment

But both of those wavelengths can be created in a Nd crystal at the same time. Why would you want to have two and then go to the trouble of combining them?

Default Re: SFG experiment

Perhaps to induce lasing action in the secondary crystal, while being able to control the line dominance ratio within the cavity.

Need a proper line power ratio to achieve an optimized SFG on a specific line? Can't find the proper coatings on all the optics that you'll need?

Maybe it could help.

What do you think Cyp?

Default Re: SFG experiment

Assuming the 1064 was typo'd, this is 589 we're talking about which is a well established process. I'm all for improvements to existing tech, but doubling the materials cost and adding many alignment steps in exchange for a moderate increase in efficiency seems silly to me.
