A fiber laser-pumped high-power burst-mode-operated picosecond mid-infrared (IR) laser at 3. 8 μm is reported. A gain-switched distributed Bragg reflector laser diode with a pulse repetition rate (PRR) of 138 MHz and pulse duration around 200 ps was applied as the seed laser of a master oscillator power amplifier (MOPA)-structured Yb fiber laser. https://parisnaturalfoodes.shop/product-category/ubiquinol-active-q10-100mg/
