Abstract
A scaling law model of forced evaporation in a continuously lowered optical trap was discussed. The scaling law follows from a simple energy evolution equation for the trapped atoms, which includes the energy loss. The evaporation rate of a gas from an optical trap of fixed depth stagnates as the temperature drops. The large increase in phase-space density was found to be obtained without excessive slowing of the evaporation rate.
