Achromatic waveplate
Achromatic waveplates consist of birefringent crystals of two different materials. Their different dispersions enable relatively uniform phase retardation over a broad wavelength range. Achromatic waveplates are also relatively insensitive to temperature.

Chenzheng Optoelectronics supplies precision low-order, zero-order, dual-wavelength and achromatic waveplates. Low-order waveplates introduce multiple orders of retardation, offering good mechanical strength and high laser damage thresholds. Retardance accuracy is slightly lower than zero-order plates, but lower prices provide good cost performance.

Astarphotonics offers zero-order, low-order and quartz multiple-order waveplates. A cemented zero-order waveplate consists of two multiple-order waveplates joined by cementing or optical contacting. Their thickness difference equals the thickness of a single true zero-order waveplate, and their fast axes are perpendicular. Zero-order waveplates produce zero-order phase retardation and outperform multiple-order waveplates, with broader bandwidth and lower sensitivity to temperature and wavelength changes.

Ytterbium‑doped fiber serves as the core energy‑conversion component inside a fiber laser. Pump light emitted by laser diodes is coupled into the gain fiber, and energy is transferred to signal laser beams via ytterbium ion energy‑level transition for power amplification.
