Tunable Continuous-Wave Optical Parametric Oscillator Laser from Visible to Mid-Infrared - Type of laser system: Continuous-wave, continuously tunable across the ranges of desired wavelengths in the visible and near-infrared. Required wavelengths and power: • Laser system must have one or several windows of continuous wavelength tunability, such that the system covers >75% of the wavelength range (the 75% measured in wavelengths) from 500 nm to 3.5 microns. • Laser system should cover >80% of the wavelength range from 500 nm to 750 nm. • Laser system must have output >=500 mW at wavelengths ~780 nm, ~1064 nm, and ~1560 nm. • Power >=300 mW across >80% of the covered wavelengths, where “covered wavelengths” refers to range(s) over which the laser system has continuous tunability • Power >=500 mW across >50% of the covered wavelengths, where “covered wavelengths” refers to range(s) over which the laser system has continuous tunability • Power >=1 W across >20% of the covered wavelengths, where “covered wavelengths” refers to range(s) over which the laser system has continuous tunability • At least one laser line between 532 nm and 1064 nm must have power >5 W. • At least one laser line between 1064 nm and 3500 nm must have power >10 W. • Linewidth: <= 1000 kHz for all wavelengths • Accuracy of frequency, when selecting a frequency in software <= 2 THz for all wavelengths • Beam quality: TEM00, M2<=1.5 for all wavelengths • Polarization: Linear • Noise: <=1% rms • Footprint for laser head on optical table: less than 4 ft by 4 ft
