By virtue of having no moving parts our acousto-optic modulators (AOMs) are able to amplitude modulate a laser beam at very high speed. For example modulation bandwidths in excess of 50MHz are readily achievable.
1. Free-space Acousto-optical Modulators
We offer a wide range of standard AO Modulators, for digital or analogue intensity modulation of laser beams. Their main specifications are as follows:
Wavelength Range: 240nm to 2100nm
Drive Frequencies: 20MHz to 350MHz
Optical Rise-Times: Down to 5ns
Modulation Bandwidths: Up to 100MHz
Interaction Materials: Tellurium Dioxide, Lead Molybdate, Fused Silica, Crystal Quartz, Chalcogenide Glass, Flint Glass.
2. Fiber-coupled Acousto-optical Modulators (AOM)
We offer a wide range of standard fibre-coupled AOMs with the following characteristics: -
Wavelengths: 1000-1100nm, 1310nm or 1550nm
Drive Frequencies: 40MHz, 80MHz or 110MHz
Optical Rise-Times: as low as 10ns
Materials: Tellurium Dioxide & Chalcogenide Glass
