MAGNETO-OPTIC TRAP OF RB ATOMS WITH AN INJECTION-SEEDED LASER THAT OPERATES AT TWO FREQUENCIES

摘要

We captured Rb atoms in a magneto-optic trap by using two frequencies in an injection-seeding process of a diode laser without the use of a separate repumping laser. In the incomplete injection-seeding condition, the pow er of the free-running slave laser at the repumping frequency can be partially converted into power at the master laser frequency, which is stabilized at the cooling frequency. We measured conversion efficiencies and frequency shifts based on the injecting power and the preset frequency difference between the master laser and the slave laser.
