1 GHz Laser Quantum laser and finesse pure CEP used to create a frequency comb


Recently published work has been conducted using Laser Quantum’s 1 GHz gigajet laser and its finesse pure CEP to create a frequency comb.Recently published work by Brigham Young University, Utah, USA, has been conducted using Laser Quantum’s 1 GHz laser (gigajet) alongside its finesse pure CEP laser to create a frequency comb. Frequency combs are instrumental to precise laser frequency measurements and have led to giant steps forward in research in applications including; metrology, atomic clocks, laser spectroscopy and astronomy. Both of the published works look at precision spectroscopy using an optical frequency comb. The gigajet, a femtosecond oscillator in a temperature controlled housing, ensures a stable performance over long periods of time. The finesse pure CEP, with its ultra-low noise and high pointing stability, makes an exceptional Ti:Sapphire pump.

The taccor, the latest generation of 1 GHz repetition rate lasers, delivers more than 1.6 W of average power with pulse durations of <60 fs. The taccor range of lasers are excellent femtosecond lasers, with integrated pump sources in hermetically sealed cavity’s.

Laser Quantum also offer a complete frequency comb solution, the taccor comb. This is a powerful, 1 GHz turn-key Ti:Sapphire laser with matched dispersion compensation module, super-continuum generation and ultra-stable f-to-2f interferometer. It provides an electrical output signal at the carrier-envelope offset (CEO) frequency with at least 40 dB signal-to-noise ratio in 100 kHz bandwidth. An excellent extension to the already successful taccor range.
