Method of driving a semiconductor laser. |
| 摘要 |
<p>A semiconductor laser oscillating in a single mode under direct-current drive is driven by a signal in which a high frequency current is superposed on a direct current, so that the laser is brought into continuous wave pulsed oscillation at a pulse width of at most 1.2 ns, whereby laser noise is suppressed.</p> |
