Superior Reliability & Performance

 

Coherent’s team holds extensive expertise in optically pumped THz generation.  With our systems capability, this team has designed and developed a THz local oscillator that was launched into orbit and is currently operational on a satellite circling the globe (see the paper below). Optically pumped THz generation offers the advantage of both high power and CW operation, ideal for development of solutions for security, non-destructive testing, imaging, and medical applications. Contact Coherent if you have a high power source requirement and would like to leverage Coherent’s expertise in this area.

The SIFIR-50 Laser System brings reliable, easy operation, stable output, and outstanding beam quality to the scientific and commercial THz application user. The SIFIR-50 package is rugged, and transportable.

The SIFIR-50 is an optically pumped THz laser consisting of a sealed-off pump laser, a frequency standard, and a THz laser cavity. The pump laser inside the SIFIR-50 features an efficient folded resonator approach contained within an all-metal housing. Metal seals insure both long operational and shelf lifetimes. This structural approach gives the SIFIR-50’s pump laser its outstanding beam quality and stability.

The controller module contains all of the electronics necessary to support the laser head, including the solid-state RF power supply for the pump laser, the pump laser frequency-control electronics, and the user interface displays.

The superior performance of the SIFIR-50 laser technology has made it the THz source of choice for a wide range of demanding applications?from a 5-year atmospheric measurement mission on NASA’s AURA Satellite to characterizing advanced next-generation devices and materials for telecommunications.
