摘要：
An absolutely stabilized laser diode system for high-resolution spectroscopy of the 4(2)S(1/2)-3(2)D(5/2) electric-quadrupole-allowed transition in calcium ions at 729 nm is developed. Both its short-term and long-term stabilities are examined. A system for laser cooling of single calcium ions using an ultraviolet laser diode for excitation of the 4(2)S(1/2)-4(2)P(1/2) transition is also constructed, and by using it we have observed quantum jumps of single calcium ions with a high stability and a high signal-to-background ratio.
