H-SMART flexible design and microprocessor controlled operation enabled us to implement number of advanced features:
Single output port – motorized selection of required wavelength, emitted trough the same exit aperture.
Self-tuning – automatic, microprocessor controlled tuning of non-linear crystal temperatures for maximum pulse energy.
Monitoring – monitoring of pulse energy at fundamental or harmonic wavelength.
Bypass – laser fundamental beam can bypass H-SMART with minimal losses on internal optical components.
Attenuation – ability to attenuate output pulse energies without change of laser pump energy, helping to minimize changes to beam profile and pulse duration.
Enhanced spectral purity– improved to 99.9% spectral purity of exit wavelengths.
“Features” table below summarizes features of each model and available extensions.
