We have conducted experimental investigations on the effect of repumping laser on the cooling and trapping of strontium atoms. More than 3.1×10888Sr atoms have been trapped with 679 nm and 707 nm repumping laser added. The two repumping lasers enhance the trappopulation by a factor of 17. We also made experimental investigations on the effect of 707 nm repumping laser detuning on the cooling and trapping of strontium atoms. The fluctuation of atom trapping population is less than 3 ‰ when the detuning from 707 nm is 5 MHz.
