Hello!
I don´t understand the hype becouse of the 500mW Mitsubishi diodes.
Still the 500mW CW Diode has a emitter of 40*1µm !
This diode isn´t usuable for a lasershow use. The best beam you will get out with best optics will be arround 4*4mm @ 2,5mrad...
Still this is a single emitter - multimode - broadband emitter Diode. To produce red on a highpower level with small emitters is a very difficult thing, it is not more possible what is avaiable at the moment !
The Casio diode has a single emitter 1*14µm - 1*15µm... And still look which beam you get out ... the 500mW Nichia is 7*1µm and the Opnext/Mitsubishi diodes which we use are 2*1µm-3*2µm max.
If you collimate it and run it you see beams side by side, this are Modehops ! As the DPSS lasers also the diodes arent perfect - they aren´t 100%ly linear and they have modehops!
Greets,
