Embodiment Construction
[0017] see figure 1 , the present invention provides pulse electric energy through a power supply and its control circuit, including several pulse segments, wherein each pulse segment includes a series of sub-pulses 1, 2, 3, 4... whose pulse width increases with time, and the average power of the above-mentioned sub-pulses decreases with time, while the pulse width increases with time, making the energy constant over time. The above multi-pulse electric energy is applied to the pulse lamp to obtain energy-balanced multi-pulse intense light; using the pulse lamp as the pump lamp of the solid-state laser to output the above-mentioned multi-pulse strong light can make the solid-state laser output the energy balance of the aforementioned pulse characteristics multi-pulse laser.

The invention discloses energy-balance multiple-pulse intense light or laser and a method for generating the same. The multiple-pulse intense light or laser comprises a plurality of pulse bursts, wherein each pulse comprises a plurality of subpulses; and the intensity of each subpulse decreases gradually with time, and the pulse width of each subpulse increases with time so that the energy of eachsubpulse keeps balance. The generation method comprises the following steps: providing a power supply with the pulse characteristics; then applying the power supply to a pulse lamp; and taking the pulse lamp as a pumping lamp of a solid laser so as to generate energy-balance multiple-pulse laser. The energy-balance multiple-pulse intense light or pulse laser ensures the energy balance of each subpulse in each pulse burst, and thus the multiple-pulse intense light or laser of which the energy always keeps stable and balance can be acquired so as to control the intense light or laser easily, ensure the stable effect during the treatment of the intense light or laser and also operate a number of relatively precise curative schemes.
Description
technical field [0001] The invention relates to a method for generating intense light or laser, in particular to a method for generating multi-pulse intense light or laser. Background technique [0002] In the prior art, the laser or strong light therapeutic apparatus used for clinical treatment adopts multi-pulse strong light or laser, and each pulse segment contains several sub-pulses, and the pulse energy when multi-pulse strong light or laser is generated is within one pulse segment. The medium decreases with time, resulting in the instability of the pulse energy that appears sequentially in time, thus affecting the treatment of strong light or laser. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a strong light or laser and its generation method which can keep the pulse energy always stable, so that the laser or strong light therapeutic apparatus can obtain better therapeutic effect. [0004] The present i...
