Using piezoelectric to power a laser diode?

Hi,

I'm a complete novice/noob to electronics.

I have a little project i'm working on, and would like to use a
piezoelectric power source to run a small visible laser diode for a
short duration (20-200ms). Does this seem feasible? The biggest
problem, from what i can tell, is the output voltage of the piezo is
likely to be much greater than the 2-3V i need to run the diode. The
other problem i'm having is actually finding suppliers of piezo devices
that would be suitable for this...all i can find are accelerometers and
strain gauges.

Any thoughts? The energy source will be a sharp blow from a small
spring-loaded lever.

Thanks!
