Hi there……….Bob its the 980 nm wavelength not the 908nm……..its the diode by Biolitec that is 980nm.

Just wanted to clarify because otherwise newbies might get confused.

810 nm diodes (many available in this range )
980 nm diode (Biolitec, also soon Deka)
1064 Nm NdYag

All are soft tissue lasers.

PS great stuff Ron , great to have your knowledge for literature on lasers out there.
