Abstract

We demonstrate direct generation of sub-40 fs pulses from a diode-pumped mode-locked laser using an ytterbium-yttrium codoped multi-component alkaline-earth fluoride crystal and a semiconductor saturable absorber mirror. The Yb,Y:(Ca,Sr)F₂ laser delivers soliton pulses as short as 35 fs at 1056.7 nm, with an average output power of 182 mW at a repetition rate of ∼65.7 MHz. By increasing the transmittance of the output coupler, the average output power scales to 322 mW at a somewhat longer pulse duration (49 fs) at 1052.5 nm, corresponding to a peak power of 87.9 kW and an optical efficiency of 32.4%. To the best of our knowledge, these are the shortest pulses from a Yb-doped alkaline-earth fluoride crystal.

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.
