| 摘要 |
<p>The invention relates to a laser device for emitting pulses of variable period and stabilized energy, which comprises a resonant cavity (1) comprising an amplifying medium (11) that has a stabilized gain G and emits laser pulses at a wavelength ?, the resonant cavity (1) further comprising a Q-switch (12). The laser device also comprises a pump (2) for continuously pumping the amplifying medium, and an injector (3) that is placed outside the resonant cavity (1), injects a beam of wavelength ? into the amplifying material (11) over the duration of the pumping process, and includes means for adjusting the power of said beam in order to reduce the gain of the amplifying medium to G/k, where k is a real number greater than 1.7.</p> |
