Abstract
A 2.4 GHz Kerr-lens mode-locked laser, employing Yb:Y2O3 ceramic as the gain medium, has been fully integrated into a compact 61 mL volume. By optimizing the pump structure, all optical components of the laser are confined within a 34 × 78 mm2 area, enabling effective temperature control. Owing to the temperature control, the repetition-rate drift of the laser in free-running mode can be as low as ∼10-8 with a timing jitter of 13 fs. Furthermore, this laser operates with a low electrical power consumption of only 4 W. All these attributes make this Kerr-lens mode-locked laser a portable low-noise signal source. In addition, the laser operates around the central wavelength of 1075 nm and has a spectral width of 11.2 nm. The relative power stability of the laser in 2 h is within 0.4%.
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.
