  • ULTRA-HIGH-POLARITY CHIRAL LIQUID CRYSTAL MATERIAL, LIQUID CRYSTAL LASER AND PREPARATION METHOD THEREFOR
    Publication number: 20240019746
    Abstract: The present invention discloses an ultra-high-polarity chiral liquid crystal material, a liquid crystal laser and a preparation method therefor. The ultra-high-polarity chiral liquid crystal material has, in a certain temperature range, a high dielectric constant of ?˜104 and a characteristic of extremely-strong second harmonic response 3 to 10 times as much as that of a quartz crystal, and a pitch of the ultra-high-polarity chiral liquid crystal material is adjusted within 0.1 to 1 micrometer according to a doped concentration of the chiral molecule.
