A diode is a semiconductor. http://en.wikipedia.org/wiki/Diode
A LED is a light emitting diode.
A LD is a laser diode.
The average person can easily get all different types of inferred, red, and violet ("blu-ray") LD's
Because of the vast amount of research and development required and lack of demand for other laser diodes, it's safe to say they just don't exist, although there are green and blue laser diodes I have yet to hear anybody spending thousands of dollars on one.

However, by that time Sony (and everyone else) had settled on the DVD standard, so there wasn't much point in mass manufacturing the expensive LD for only a minor improvement in capacity.
