A laser-pointer may do the job(*) but the one I have access to is bigger (though perhaps not better(*): * = The job is to send a beam of laser light through a sample of CS and determine the characteristics of the CS by analyzing the pattern of scattered light coming out the other side of the sample (in a clear container). Lasers have a few main characteristics, one of them is "stability" - which is how well they stay in the same frequency and mode/phase. If the laser keeps changing phases and modes it may be more diffecult to interpret the scattering. Some lasers are "mode locked" and some are not. I will find out about all this and report back to the group here in detail. It could be that the cheap laser pointers (about us$50) will do the job well. Interpretation is another matter, stay tuned... -- Richard [email protected]
