abstract

  • Secondary laser cooling has been realised on the weak dipole transition 4f 13 ( 2 Fo)6s 2 , J = 7/2, F = 4 4f 12 ( 3 H 6 ) 5d 5/2 6s 2 , J' = 9/2, F' = 5 with the wavelength of 530.7 nm and natural width of 350 kHz. The temperature of the atomic cloud in a magnetooptical trap (MOT) was 30 K at the lifetime of 2 s and the number of atoms 105. Approximately 1 % of atoms from the MOT have been reloaded to an optical dipole trap and to one-dimensional optical lattice at the wavelength of 532 nm. The atom lifetime in the optical lattice was 320 ms. We propose to employ thulium atoms captured in an optical lattice as an optical frequency reference. 2014 Kvantovaya Elektronika and Turpion Ltd.
