摘要： PROBLEM TO BE SOLVED: To provide a laser oscillation optical device with a low light stimulation energy threshold value that eliminates the need for an optical resonator employing a chiral liquid crystal. SOLUTION: Although a conventional system for applying optical stimulation to the chiral liquid crystal added with a laser oscillation luminescent material applies linearly polarized light to the chiral liquid crystal to stimulate laser, the laser oscillation optical device applies optical stimulation to the chiral liquid crystal with circularly polarized light in a direction opposite to the molecular chirality of the chiral liquid crystal to stimulate laser with a high efficiency.
