The main technical parameters:
1. Wavelength: 808nm diode laser manufacturers tell you the working wavelength of the laser tube, there are many kinds of laser tube wavelengths that can be used as photoelectric switches.
2. Threshold current: that is, the current that the laser tube starts to generate laser oscillation. For general low-power laser tubes, its value is about tens of milliamps, and the threshold current of laser tubes with strained multiple quantum well structures can be as low as 10mA or less.
3. Working current: that is, the driving current when the laser tube reaches the rated output power. This value is more important for designing and debugging the laser driving circuit.
4. Working voltage: The 808nm diode laser manufacturer tells you the forward voltage required to emit the specified light output.
5. Optical output power: the maximum allowable instantaneous optical power output. This applies to continuous or pulsed operation modes.
6. Dark current: The leakage current of the photodiode when reverse biased. 808nm diode laser manufacturers tell you that dark current depends on both temperature and voltage, an ideal diode/photodiode has no current flow in the opposite direction.
