Title:
METHOD AND APPARATUS FOR ADJUSTING OUTPUT POWER OF PULSED LASER, AND PULSED LASER
Document Type and Number:
WIPO Patent Application WO/2020/037860
Kind Code:
A1
Abstract:
A method and apparatus for adjusting output power of a pulsed laser (100), and a pulsed laser (100). The method for adjusting output power of a pulsed laser (100) comprises: if the percentage of the input power of a pulsed laser (100) is equal to zero, controlling both the current value in a first-stage optical path (12) of the pulsed laser (100) and the current value in a second-stage optical path (13) of the pulsed laser (100) to be zero; if the percentage of the input power of the pulsed laser (100) is greater than zero and less than or equal to a reference ratio, controlling the current value in the first-stage optical path (12) to be in a linear relationship with the percentage of the input power, and controlling the current value in the second-stage optical path (13) to be zero; and if the percentage of the input power is greater than the reference ratio, controlling the current value in the first-stage optical path (12) to be a first current value, and controlling the current value in the second-stage optical path (13) to be in a linear relationship with the percentage of the input power. This method implements the adjustment of the output power of the pulsed laser (100) from zero, and ensures that said output power can be adjusted to relatively low ideal output power in precision applications.
