K - The point about coherent light is it's much more wavelike (than ordinary light) due to being "in phase" and having one direction; therefore when coherent light interacts with matter the effects are much greater than for ordinary light. This is precisely the *entire point* why QDs react to laser light so intensely and why QDs (emission) can have such an effect on matter. This is why there is so much intense interest in QDs (I keep reminding you) - it is like discovering brand new atomic elements!Just Google "Quantum Dot Laser" also "quantum dot array"- it's all over the internet, has been for many years..The fact that QDs lase should not be very surprising as we have known quantum well lase since the 1970s! There is not too much difference between the well and the dot, same basic principle, altho the dot is more powerful in many respects due to better confinement.
There is quite a ways to go, we might not agree on all the pertinent points involved by Christmas :-)
