Abstract

We report the capture of cold strontium atoms in a magnetooptical trap at a rate of 3 × 1010 atoms/s. This is achieved with high power laser light at 461-nm generated by sum frequency mixing in a potassium titanyl phosphate (KTP) crystal using diode lasers at 813 nm and a Nd:YAG laser at 1064 nm. Up to 115 mW of blue light is obtained. Tuned to the 1S01 P1 of 88Sr, this light is used both to slow down an atomic beam in a Zeeman slower and to capture the atoms in a magnetooptical trap. Trapping of 87Sr and 86Sr is also reported.
