RHD,
We will be operating in ocean water, so the best color is 532nm for coastal waters and 455nm for deep ocean. The better physical characteristics of 405nm are desirable but the extra phytoplankton loss is not.
I called IXYS this afternoon and was told that the IXLD02SI was discontinued, no longer available, and that the eval board was sold out. It would have been good for preliminary testing at 17 MHz. The P3 board is much lower in frequency as noted above. Intersil said that they might have a new...
I am working on an experimental project to do both underwater communications and imaging. The laser will be using a M140 455nm diode and we need a driver that has sufficient current capacity (1.5A) and high modulation rates (100MHz). I have looked at the IXLD02SI Differential Ultra Fast...
