magneto-optical laser 中文意思是什麼
magneto-optical laser
解釋
光磁激光器-
Usually the magneto - optical trap is used to obtain the cold atoms from the vapor. it is reported that experiments for obtaining the ultra - cold cesium atoms by optical molasses directly from the vapor cell without mot. the lowest temperature achieved for the cesium atomic cloud was 3k. the relationship between the temperature and the detuning of cooling laser was measured
報告了採用直接從銫蒸汽氣室而不用磁光阱實現了光學粘團的方法。用此辦法得到了3的銫的超冷原子團。這是我國目前用激光冷卻方法得到的最低溫度。 -
But when concerned with higher magneto - optical recording density, the kerr angle become smaller at shorter wavelength than at longer wavelength result from recoding and reading the memory information by shorter wavelength semiconductor laser tube. further more the signal - to - noise of recording information lowers and brings difficulty for the reading
但在更高密度磁光記錄方面，由於信息記錄與讀出採用短波長半導體激光管，磁光記錄材料的克爾旋轉角比長波長時小，導致記錄信息的信噪比下降，給信息讀出帶來困難，為此將對材料進行改性。
