Multiple Isotope Trap from a Single Laser

Abstract

We present a system to obtain simultaneous trapping of multiple isotopes using a single laser and a fiber modulator. The system moves all the control of the beams from the optical to the RF world. Article not available.

Multiple isotope magneto-optical trap from a single diode laser

Victor Manuel Valenzuela, Saeed Hamzeloui, Monica Gutiérrez +1 more

We present a dual isotope magneto-optical trap produced using a single diode laser. We generate all the optical frequencies needed for trapping both species using a fiber intensity modulator. All the optical frequencies are amplified simultaneously using a tapered amplifier. The independent control of each frequency is on the RF side rather than on the optical side. This introduces an enormous simplification for laser-cooling applications that often require an acousto-optic modulator for each laser beam. Frequency-changing capabilities are limited by the modulator bandwidth (10 GHz). Traps for more isotopes can be simply added by including additional RF frequencies on the modulator.

Effective multiple sideband generation using an electro-optic modulator for a multiple isotope magneto-optical trap

Aiko Uchiyama, K. Harada, Kosuke Sakamoto +8 more

Herein, we report an effective method for the generation of radio-frequency (RF) sidebands in an electro-optic modulator for the simultaneous magneto-optical trapping of two isotopes. This is achieved by switching the RF signals alternately, which suppresses the generation of unwanted frequency signals and improves the laser power per sideband. The generated sidebands are successfully applied to a dual-rubidium-isotope magneto-optical trap (MOT), which results in an increased number of trapped atoms. This simple, flexible, and robust technique can be implemented in experiments that require a large number of atoms in multiple-isotope MOTs and for various applications.

A simple atom trap using frequency modulated diode laser

W. Jhe

We have built a compact extended cavity diode laser system having microwave sidebands. Using the laser system, we could separate two stable isotopes of rubidium simultaneously trapped in a magneto-optical trap. We also have realized a very simple atom trap in a pyramid-shaped hollw mirror system and a conical hollow mirror using a single beam.
