Why Metrological Traceability Matters in Medical Laboratory Diagnostics

The Journal of Applied Laboratory Medicine
Abstract Application of the results provided by medical laboratories plays an essential role in medical decision-making. This is not limited to diagnosis and monitoring of disease but also involves its use in other phases of the health continuum, e.g., predisposition, risk stratification, screening, staging, prognosis, and ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser

Laser &Photonics Reviews, EarlyView.
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser

Laser &Photonics Reviews, EarlyView.
Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route

Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

Laser &Photonics Reviews, EarlyView.
Independent control of the repetition rate and offset frequency is demonstrated in quantum cascade laser frequency combs using radio‐frequency injection and thermal tuning. A revised comb model anchored at optical frequencies captures the unique behavior under radio‐frequency injection and enables precise frequency control.
