| 英文摘要 | A diode laser writer having a high speed, high current, precision laser driver provides for switching a constant current source between a write laser and a dump load. An inductor is provided in a leg of the circuit such that the inductor and the constant current source form a series circuit with whichever of the dump load and the write laser that is switched ON. The inductor keeps the current constant because the inductor produces an e.m.f. counter to the e.m.f. of the load inductance. The added inductance will generate an e.m.f. counter to that of the load inductance, serving to augment the compliance voltage. The overall effect of the added inductor is to restore the constant current property of the circuit. |
