Description
まず、図1で示される光学系において、中心波長1064nmのNd:YVO4レーザーを、螺旋状位相板(SPP)とλ/4板、対物レンズ(NA〜0.65)を使用し、これらを通してグリシンを重水に溶解度まで溶解させたアミノ酸飽和重水溶液(プレパラート上に塗布)に照射した。アミノ酸飽和重水溶液に照射しているレーザーのスポットの径はφ3μmとした。また円偏光の向きと光渦の螺旋波面の向きは同じ方向に設定した。なお円偏光光渦は、SPPによって得られる軌道角運動量(l=−1又は1)とQWPによって得られるスピン角運動量(s=−1又は1)の総和である全角運動量(J=l+s)の大きさを変更して照射することができる構成となっている。
この結果を図2にそれぞれ示しておく。
上記グリシンの例において、レーザーを直線偏光のガウスビームを用いた以外は同様の条件でアミノ酸の結晶の作成を試みた。この結果を図3に示しておく。この結果によると、アミノ酸は析出したが明らかに多結晶のものであった。
Claims (1)
- 円偏光の光渦を、アミノ酸飽和溶液に照射して、前記アミノ酸飽和溶液中にアミノ酸の結晶を形成する、アミノ酸結晶の製造方法。
