[Laser] AOM

Fri, 26 Sep 2003 23:15:38 +0000 (UTC)

	Dear L.,

	It depends on a lot of factors:

	a] What the AOM is made from and
	b] its transmission wavelength[s] or  abbreviated as WL.
	c] ythe optical set up or design
	d] it may well polarize the beam and if you rotate one or the
other you may get better through beam

	you MUST define the materials and design for me to be able to give
accurate info.

	I have not been follow this thread.

			Best,

					JH
