What Are the Key Factors to Consider When Selecting a Narrow Linewidth Laser?When selecting a narrow linewidth laser, several key factors should be considered to ensure that it meets the specific requirements of the application. These factors include: l Linewidth: The required linewidth depends on the application. For example, high-resolution spectroscopy may require a linewidth of less than 1 MHz, while less demanding applications may be able to...0 Commentarii 0 Distribuiri 4K Views

The Role of Rare-Earth Dopants in Ultra-Narrow Linewidth Single-Frequency Fiber LasersUltra-narrow linewidth single-frequency fiber lasers rely heavily on rare-earth-doped gain fibers to achieve high coherence and stable operation. The choice of dopant (e.g., erbium, ytterbium, or thulium) significantly impacts laser performance, particularly in linewidth narrowing. Key Rare-Earth Dopants and Their Properties Erbium (Er³⁺) – Operates in the C-band (1530-1565...0 Commentarii 0 Distribuiri 1K Views
