AI Article Synopsis
- Researchers developed a powerful bulk laser using Ho:CALGO that operates at a wavelength of 2.1 µm, producing 2 W of average power with 112 fs pulse duration.
- This laser stands out as the highest average power output from a mode-locked laser in the 100-fs category using Tm or Ho doped materials.
- It features impressive noise performance, including 0.02% intensity noise and 950 fs timing jitter, making it suitable for various applications.
Article Abstract
We report on an in-band pumped soft-aperture Kerr-lens mode-locked Ho-doped CaGdAlO (Ho:CALGO) bulk laser at 2.1 µm, generating 2 W of average power with 112 fs pulses at 91-MHz repetition rate. To the best of our knowledge, this is the highest average power from a 100-fs class mode-locked laser based on a Tm or Ho doped bulk material. We show that the laser has excellent noise properties, with an integrated relative intensity noise of 0.02% and a timing jitter of 950 fs (rms phase noise 0.543 mrad) in the integration interval from 10 Hz to 10 MHz of offset frequency. The demonstrated combination of high average power, short pulses, and low noise makes this an outstanding laser source for many applications at 2.1 µm.

Phenolic acid-rich fraction from Anisopus mannii (PhAM) contains abundance of ferulic acid, gallic acid, protocatechuic acid, and syringic acid. Among other glycolytic enzymes, in vitro, PhAM counteracted the binding of sodium orthovanadate to phosphofructokinase 1 (PFK-1), improving its activities. In a rat model of diet-induced diabetes, PhAM monotherapy reduced HbA1c by an average of 0.
