Technical Advantages of Dual Wavelength Waveplate:
The dual wavelength waveplate achieves simultaneous precise phase retardation ( λ/4 or λ/2) for two specific wavelengths (such as fundamental and frequency-doubled light) through sophisticated optical design. Its technical advantages include optimizing thickness matching with birefringent materials like quartz and mica, ensuring phase retardation errors of less than 3% at both wavelengths. The compact structural design eliminates losses from stacking traditional single-wavelength waveplates, with a volume only half of combined schemes. In laser processing, it simultaneously controls the polarization states of 1064nm fundamental light and 532nm frequency-doubled light, enhancing material absorption of dual-wavelength energy. In WDM fiber communication systems, it supports polarization multiplexing for 1310/1550nm dual wavelengths, reducing optical components and insertion loss to achieve polarization-dependent loss (PDL) below 0.5dB, significantly enhancing transmission stability for dual-band signals.
