Technology's not quite there yet to make it worthwhile to combine hundreds of tiny emitters with insane optics... might as well just get a CO2 tube with a huge electric hookup and call it a day
Idk how you'd make that into 445nm tho
Yes the technology is common place, your typical active fiber laser is pumped via. hundreds of small emitters knife edged and fiber coupled, that's what's inside most of the industrial FC IR laser pumps, many small lasers bundled with optics.
He could use a big YAG and pump a SHG crystal for 450nm but it would be expensive.
C02 centers around 10200nm although I see some tubes advertised as 10600nm so that's not useful unless you can make 450nm from 10.2um
Actually there was a discussion about the isotopes contained in carbon dioxide molecules which account for the emission range which can range from 9.0 - 10.2um depending on the combination, still I don't know how you would make 450nm from that.
