Evaporative cooling by pulse width modulation (PWM) of optical dipole traps
S. Sagar Maurya, Joel M. Sunil, Monu Bhartiya +4
We introduce a method for cooling atoms in an optical dipole trap using pulse-width modulation (PWM) technique, without reducing the laser power of the dipole trap. The PWM techniq…
