Now that 405nm modules are available, has anyone exprimented with colour mixing of RGB lasers each being PWM? I assume this is possible since LEDs which are also current driven use this technique to achieve various intermediate colours. I know that others have used individual R, G and B lasers to produce cyan, magenta, yellow and white from the primaries but I would have thought that all other colours could be mixed if each beam was individually modulated then mixed.
Thanx for the pointer rog8811. A quick google proves that solid state lasers are often modulated by PWM but as to colour mixing, that doesn't get much of a mention other than straight primary mixing which you have amply demonstrated. I hope to have some time in the future to muck around with various mixing experiments and see what transpires.
Keep up the good work and congratulations on constructing a first class device!
