I think these are way to expensive. I was explicitly thinking about these engineering sample 480nm SM diodes that where relatively cheap.Nichia used to have a 20mW 473n back in 2009 now obsolete.
You can try asking Franfurt Laser Co if they have any and at what cost. ---they show 100mW, 300mW and 1W 473nm diodes.

Yes expensive if Thor labs price of $2,762 for a Nichia NDA4116 100mW SM 473nm is anything to go by https://www.thorlabs.com/thorproduct.cfm?partnumber=L473P100 They don't even show the NDA4216 200mW 473nm Nichia diode, so...I think these are way to expensive.

Got it.I see.
I think it’s worth a try to ask if someone has one lying around. The 488nm diode is nice, but not interesting. I do allready own one. I would like something much deeper. More like 473nm.
What you want doesn't exist unfortunately--low cost, wavelength not mass produced that almost nobody needs or uses , and a few mW --Yes this would be a option, however I don't like the power.
I would only want a few mW not 1,5W.
