Does anyone know or have references to articles/information about refractive
index dependency on pressure in solids (glasses, quartz)?

For gases there exist models which describe this dependency, but for solids
I couldn't find anything so far. I know that stress induced birefringence
also is a pressure effect, but I am looking for nominal refractive index
changes, not differences for polarisations.

Best regards,
Rob.

The Schott catalog has a description. It also mentions a Technical Memo
TI Nr.20/1988 that may
provide more information (available from Schott Duryea, I think).

Hi Rob:

Look in:
Staudenraus, J.; Eisenmenger, W.:
"Fiber-optic probe hydrophone for ultrasonic and shockwave measurements
in water."
Ultrasonics, Vol. 31, No.2. p267-273, (1993)

Water:
Delta n / Delta p = 1.35x10^-4 1 / MPa

Silica glass:
Delta n / Delta p = 5x10^-6 1 / MPa

Should be valid around 780 nm.
