Transverse mode instability (TMI) free high power operation of 85μm core Yb-doped chirally-coupled-core fiber amplifiers

Mingshu Chen, Christopher Pasquale, Jack R. Crandall, I-Ning Hu et autres

We report a TMI-free continuous wave operation of 1.9m-long 85μm core Yb-doped chirally-coupled-core (CCC) fiber amplifier with 333W single mode beam quality output, limited by available 976nm pump power but not the onset of TMI. This is a significantly higher power than …

A monolithic linearly polarized counter-pumped 85 µm core rod fiber amplifier architecture for high-energy pulsed applications

Carson J. Shollenbarger, Jason D. Tafoya, Brian M. Schulz, D. Schulz et autres

In this work, we discuss a novel architecture for an all-fiber linearly polarized counter-pumped linear amplifier utilizing an 85 μm core diameter rod fiber. Signal light is launched directly into the core region of the rod fiber with high coupling efficiency via …

PM 56/400 Yb tapered fiber monolithic amplifier in a pulsed MOPA configuration for high energy/power applications

Brian M. Schulz, John Pickron, D. Schulz, Carson J. Shollenbarger et autres

We demonstrate that the PM 56/400 Yb tapered fiber achieves a good combination of large mode field diameter and beam quality for use in a pulsed, monolithic fiber amplifier. We evaluate this fiber over a wide test regime to determine its viability …

Retrograde headless compression screw fixation of olecranon stress fractures in throwing athletes: a novel technique

Richard M. Michelin, Isaac Manuputy, Brian M. Schulz, Mark Schultzel et autres

Background: An olecranon stress fracture (OSF) is a rare injury most commonly seen in high-level overhead throwing athletes with no clear consensus on surgical treatment. The most common surgical treatment described in the literature is cannulated screw fixation but there have been …

All-fiber integrated 85um core chirally-coupled core fiber high energy amplifiers for compact coherently combined laser arrays

Mingshu Chen, Alexander Rainville, Manoj Kanskar, Ossi Kimmelma et autres

We report development of 85µm core Yb-doped and Ge-doped chirally-coupled-core (CCC) fibers, and their integration via fusion-splicing into an all-fiber optical amplifier system. This system, consisting of a CCC fiber amplifier and a 6+1 fusion-spliced signal-pump-combiner with a passive CCC fiber feed-through …

The Ulnar Collateral Ligament Responds to Stress in Professional Pitchers

Joy English, Daniel M. Cushman, Chong Zhang, Angela P. Presson et autres

Objectives: It remains unknown whether the frequently injured ulnar collateral ligament (UCL) responds to the stress of baseball pitching. Our purpose was to determine the response of the UCL in professional pitchers to pitching and rest. Methods: In a prospective study supported …

The Ulnar Collateral Ligament Responds To Stress In Professional Pitchers

SATPeter Nissen Chalmers, Joy English, Daniel M. Cushman, Steve H. Yoon et autres

Objectives: The ulnar collateral ligament (UCL) is one of the most common sites of injury in baseball pitchers, with 25% of Major League Baseball (MLB) pitchers having undergone surgical reconstruction (UCLR). It remains unknown whether the ligament responds to the stress of …

Relationship Between Glenohumeral Internal Rotation Deficit and Medial Elbow Torque in High School Baseball Pitchers

D. Grace Smith, Alexander J. Swantek, Caleb M. Gulledge, Vincent A. Lizzio et autres

Background: Alterations in throwing mechanics have been identified as a risk factor for overuse injuries in baseball players. Glenohumeral internal rotation deficit (GIRD) has been found to adversely affect throwing mechanics, but the effect of GIRD on medial elbow torque is unclear. …
