Lowest divergence laser diode?

[paul1598419]

I've got to agree. The DPSSLs have the best beam profile and lowest divergence of all my lasers by far. I have many 532nm DPSSLs and they all have a very tiny beam that diverges very little over long distances regardless of the power.

My best is the 650nm DX dilda. Not sure which diode is in it, but it beats all 532nm DPSS's that I have.

My best right now is my 589nm Spartan. The divergence is insanely tight on this badboy!
