摘要

We report a compact source of high power, tunable, ultrafast yellow radiation using fourth-harmonic generation of a mid-IR laser in two-stage frequency-doubling processes. Using Cr2+:ZnS laser at 2360 nm frequency-doubled in a multi-grating MgO:PPLN crystal, we have generated near-IR radiation tunable across 1137-1200 nm with average output power as high as 2.4 W and pulse width of similar to 60 fs. Subsequently, the near-IR radiation is frequency-doubled. using a bismuth triborate (BIBO) crystal to produce coherent yellow radiation tunable across 570-596 nm with a maximum average power of similar to 1 W. The source has a maximum mid-IR to yellow (near-IR to yellow) single-pass conversion efficiency as high as similar to 29.4% (similar to 47%). Without any pulse compression, the yellow source has output pulses at a repetition rate of 80 MHz with a pulse width of similar to 130 fs in Gaussian-shaped and a spectral width of similar to 4 nm corresponding to a time-bandwidth product of 0.45. The generated output beam has a Gaussian transverse beam profile with measured M-2 values of M-x(2) similar to 1.07 and M-y(2) similar to 1.01. (C) 2020 Optical Society of America
