Current diode state of the art?

[michaelh-new]

I've been out of the hobby for way too long but was curious about the current state of art regarding diode lasers.

Are there any available > 20mW that are both in hobbyist price range that provide stable beam output for holography?

Look at those from PD Controls.

I don't know about diodes but checkout this small dpss green laser.

They were being sold relatively cheaply at one point <£100
