With Marta Csatári and Steve Hutchins, Ross reported a multipass optical amplifier combining high gain and stable output. The abstract gives saturated gain above6000 and output stability of0.2% rms over the shorter measurement interval and0.7% rms over the longer one under the reported conditions.^[ref]

An original interpretation example distinguishes stability from absolute accuracy. If a readout has mean100units and relative standard deviation0.2%, its standard deviation is0.2units. A constant calibration error could shift every reading together while leaving that relative fluctuation small. A stability figure consequently does not by itself establish the correctness of the absolute output scale.

Ross also worked with John Collier on optical parametric chirped pulse amplification, as documented in the facility's historical account.^[ref] These contributions connect amplifier design with the need to control and characterize the pulses it produces. Gain, stability, spectrum and temporal shape describe different aspects of performance.
