Single-cavity Laser Emits High-Power, Dual-Comb Femtosecond Pulses

Facebook X LinkedIn Email
Researchers at ETH Zurich have developed a method that uses a single laser cavity to create two high-powered optical frequency combs, emitting high-power femtosecond pulses. The advance supports potential future developments that move toward designing more compact dual combs that offer flexibility in power, wavelength, bandwidth, and pulse repetition rates. Those combs would be able to support development of dual-comb light sources for spectroscopy and precision distance measurements. The researchers used a single laser cavity multiplexed with birefringent calcite crystals to allow for...Read full article

    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
