Mackenzie1 TITLE:Highly efficient 110-W closed-cycle cryogenically cooled Nd:YAG laser operating at 946 nm JOURNAL: Optics Letters PAPER DOI IF KNOWN:https://doi.org/10.1364/OL.401011 This dataset contains: Absorption_effciciency.csv BQ_pump_80W.csv BQ_pump_180W.csv Diode_efficiency_and_pump_absorption.xlsx Slope_effciency.xlsx Slope_efficiency_raw.csv Wavelength_data.csv Wavelength_data.xlsx The figures are as follows: Fig. 1. Schematic diagram of the experimental setup. PM1,2 are power meters, and OC is the output coupler mirror, with a dichroic mirror used to separate the residual pump and laser beams. Fig. 2. Pump beam caustics (measured in free space), and fundamental cavity modes for ROC_OC=200 mm, at 45 W and 135 W. z coordinate referenced to the input mirror position. Fig. 3. Pump absorption efficiency during lasing with two different OCs, and typical VBG-locked pump peak emission wavelength, versus incident pump power. Fig. 4. Measured laser emission wavelength (top-left axis) and respective calculated average local temperature (top-right axis), opticalto-optical efficiency (red, left axis), and output power (blue, right axis) versus absorbed pump power, for the two tested OCs.
