Image of the week: The Laser frequency comb

The Optical Society website features an image of the week, highlighting interesting and notable images within Optics and Photonics submitted by its readers. This week’s featured image was made possible thanks to one of Laser Quantum’s Ti:Sapphire lasers. The striking image, taken by Derryck T. Reid of Heriot-Watt University, is an ultra-broadband laser frequency comb from the spectrograph of the Southern African Large Telescope (SALT), located in  South Africa. SALT is the largest optical telescope in the southern hemisphere.

The image shows the lines acting as a ‘ruler’ providing a calibration scale. These ‘rulers’ in optical frequency are used in high-resolution astronomical spectrographs for applications including exoplanet hunting. Read further about how our  Ti:Sapphire pumping lasers can be used in your scientific applications.
