532nm Free-Space Acousto-Optic Modulator is used to modulate the 532nm green laser. It's free space , that means there is no fiber connected to the acousto optic modulator and the DPSS green laser.
Free space means the 532nm green laser beam from the DPSS green laser go through directly in space into the Acousto optic modulator.
Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2.Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.
