#174764 - Can I drive a Laser diode with only a resistor? |
Hello.
I have a 50mw green laser diode Can I drive it with only a resistor? There is some hazard to the diode? I have its module, so I can measure the diode current itself. I want to modulate it very fast but I think the driver is very simple and cant accept the modulation I need. Thanks. |

It is, usually... | 01/01/70 00:00 | |
| is it JUST the diode? ... | 01/01/70 00:00 | |
| Same module, another use | 01/01/70 00:00 | |
