Femtosecond vortices generated from a self-started Kerr-lens mode-locked Hermite-Gaussian thin-disk oscillator with a defective mirror.
We demonstrate the generation of stable femtosecond vortices from a self-started Kerr-lens mode-locked Yb:YAG thin-disk oscillator. By using a defective mirror inscribed with a fine line, 218-fs Hermite-Gaussian (HG) pulses are delivered directly from the thin-disk oscillator with an average power of 12 W at the repetition rate of 105 MHz and subsequently converted to Laguerre-Gaussian (LG) vortices by a cylindrical-lens mode-converter. The average output power of the Hermite-Gaussian pulses is further improved to 19 W by applying a rectangular aperture. This is the highest, to the best of our knowledge, average power obtained from any mode-locked Hermite-Gaussian oscillator to date. This work provides an effective way to generating a high-order and high-power ultrafast vortex beam.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
