Product description

The ‘Industry Standard’ Acousto-Optic Q-Switch is designed to provide reliable pulse control in high-power Nd laser systems. Its fused silica interaction material, precision optical finishing and in-house anti-reflection coatings support high transmission, low optical loss and excellent damage resistance.

Compressional acoustic mode options are suited to linear polarisation, while shear mode options support random polarisation requirements. G&H scientists and engineers are available to help specify the most suitable Q-switch and RF driver combination for each application.

Key features

  • Water-cooled acousto-optic Q-switch for high-power Nd lasers
