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 SHG (second harmonic) output that exceeds 40% efficiency and when combined with the InSight X3™, providing an average power of >800 mW at 450 nm. In addition, the new UHG Series for InSight is fully automated and allows for software control to tune both the fundamental and second harmonic wavelengths. Pulse selection is available from 340 nm to 1100 nm at repetition rates of single shot to 40 MHz. Pulse selector can run in high contrast ratio mode, or high efficiency mode depending on the needs of the experiment.

UHG Series for Mai Tai and Tsunami

The UHG Series for Mai Tai and Tsunami has been designed to handle greater than 4 W of average power and deliver efficiencies exceeding 40% for SHG. The pulse selector option inside the UHG head offers a SiO2 Bragg cell for the highest output powers and contrast ratio. The system is capable of pulse selecting from single shot to 40 MHz and is positioned before all harmonic stages to offer the most features in a single compact housing. The UHG series is a flexible system suitable for a variety of scientific applications requiring access to a wide spectrum of femtosecond or picosecond laser pulses.

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.
