I bought some laser diodes; the spec sheet says the operating current range is 25 to 75 mA. (they're 904nm)
I'm using a ddl-type constant current driver.
Tinkering around, I discovered that they still lase as low as 17mA.
What's the conventional wisdom on "under-driving" a laser diode. Is it safe, or will it damage the diode or shorten it's life?
Thanks.
