Features

UHG Series for InSight

The UHG Series for InSight provides virtually gap free tuning from 340 nm to 1300 nm when combined with the fundamental output. It provides high efficiency second harmonic generation (SHG) output that exceeds 40% efficiency when combined with the InSight X3™. The UHG series for InSight can be fully automated and tunes both the fundamental and second harmonic wavelengths. Pulse selection is available from 340 nm to 1100 nm at repetition rates from single shot to 40 MHz. The pulse selector can be used in high contrast ratio mode, or high efficiency mode depending on the needs of the experiment. For both modes of operation, the pulse selector module is positioned before all harmonic stages to offer the highest contrast ratio.

UHG Series for Mai Tai and Tsunami

The UHG Series for Mai Tai and Tsunami has been designed to handle input power levels of more than 4 W and deliver efficiencies exceeding 40% for SHG. The UHG series is a compact, flexible system that is easy to use and suitable for a broad range of scientific applications.

Compatible Power Sensors

To verify and analyze the output power of yourUHG laser, we recommend the Ophir 3A-PF-12 (7Z02720) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the UHG, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
