Spectral range: 210 nm – 2500 nm
Pulse energy: up to 250 mJ
Pulse repetition rate: up to 100 Hz
The AMETHYST platform is a laser source with a tunable wavelength, developed on the basis of an optical parametric oscillator (OPO) and a pump laser integrated into a single housing.
The AMETHYST design allows to create flexible configurationsand optimize the laser system parameters to meet your specific needs.
The basic AMETHYST configuration includes an OPO module and a Nd:YAG laser. Our model range offers lasers that provide tunable laser radiation with a pulse energy up to 250 mJ and a pulse repetition rate up to 100 Hz.
A wide range of options allows you to supplement the basic configuration with harmonic generation modules for the visible and UV spectrum ranges, spectral range selection modules and laser power attenuators.
Automated wavelength tuning and an automated laser power attenuator create additional convenience in operation and allow you to easily integrate the AMETHYST into complex laboratory & measuring systems.
The specified parameters of the AMETHYST are implemented without excessive pumping intensities. In combination with a mechanically stable positioning system for optical elements this ensures long-term and trouble-free operation without distracting the user from routine laser maintenance.
