特徴

• Wavelength plate for high power YAG laser.
• There is a lineup from fundamental wave (1064 nm) to 4 times wave (266 nm).
• By using an air gap as the bonding method for the two elements, the laser resistance has been improved.
• Since it is a zero-order waveplate, the phase difference changes due to temperature and wavelength changes are small and very stable.
• There are two types of wave plates: a 1/2 wave plate that can rotate the polarization direction and a 1/4 wave plate that can convert linearly polarized light into circularly polarized light.
• The optical element is fixed to the frame so that stress is not applied to the element when it is held in the holder.
• Both sides of the two elements (four in total) are coated with anti-reflection coating, resulting in high transmittance.
• * Before use, make sure that the energy density of the incident laser beam does not exceed the laser capacity.
• * If the laser beam is narrowly narrowed by a lens or concave reflection, the energy density may exceed the laser capacity of the device and the device may be damaged.
• * If light of a wavelength other than the adaptive wavelength is injected, the phase difference will not be as specified.
• * If the wavelength is shifted by 1%, the phase difference between the 1/2 wave plate and the 1/4 wave plate will be 1.8 degrees and 0.9 degrees, respectively.
• * The thickness of the frame (8.3 mm) may vary depending on the device specifications.
• * Do not touch the screws on the waveplate frame.
• * The characteristics may deteriorate or the device may fall off.
• * If a strong impact is applied to the waveplate frame, the axis of the element may become misaligned.
