We demonstrate laser slowing of a hot thulium atomic beam using the nearly closed cycling transition 4f(13)6s(2)((2)F(o))(J=7/2)<-->4f(12)((3)H(5))5d(3/2)6s(2)(J=9/2) at 410.6 nm. Atoms are decelerated to velocities around 25 m/s by a 40 cm Zeeman slower. The flux of slowed atoms is evaluated as 10(7) s(-1)cm(-2). The experiment explicitly indicates the possibility of trapping Tm atoms in a magneto-optical trap.
我们展示了使用近闭合循环跃迁 4f(13)6s(2)((2)F(o))(J=7/2)<-->4f(12)((3)H(5))5d(3/2)6s(2)(J=9/2) 在 410.6nm 处对热铥原子束进行激光减速。原子通过 40cm 的塞曼慢化器减速到约 25m/s 的速度。减速原子的通量评估为 10(7)s(-1)cm(-2)。该实验明确表明了在磁光阱中捕获铥原子的可能性。
