| 摘要 |
<p>This invention relates to a regenerative laser amplifier system consisting of two phase locked fibre bundle laser amplifiers (1) whose optically polished ends (2) are coupled via the microlens array (3) into the electro-optic switch (4). The said amplifiers are side excited using diode arrays (5) driven by pulsed power supplies (6). The input pulse (7) to be amplified is reflected in the said system via the polarised beam splitter (8) and becomes trapped in the system by being polarisation rotated through 90° by switch (4). After amplification to the required power level, the switching process is reversed and the amplified pulse is ejected as output beam (9). The invention has application in the industrial, defense and scientific fields where laser pulses of very high peak powers are required.</p> |
