Colloidal quantum-dots (CQDs) have emerged as promising gain media for lasers, offering low lasing thresholds, compatibility with low-cost solution-based synthesis and processing methods, and tunable ...
Schematic diagram of vertical emitting lasing from ordered InGaAs/InP multi-quantum well nanowire arrays. Simultaneous lasing is demonstrated from one same NW array. Inset shows the vertical F-P ...
Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
