If green lasers are made by going 808 to 1064 to finally 532nm using crystals and blue lasers made the same way by crystals WHY NOT VIOLET? Can someone use crystals to change an 808nm wavelength into 404nm violet because it sure seems that 808nm are cheap and powerful! If this can be done then what "crystal" would be needed to do the job...one like the blues and greens use to go from a higher nm to a lower nm by half like 1064nm to a 532nm ect...
