  1. Each laser diode package is different and usually the photodiode transfer function varies widely.
  2. Some vendors are blurring the boundaries, for example, offering USB control of components as mini-instruments.
  3. A more correct representation of noise is mA / v Hz, or current noise across a given bandwidth.

Outside of the minimum and maximum temperatures, damage can occur or behavior can change. Control System: User inputs include the limit setpoint (in terms of maximum laser diode current allowed to the laser diode), the operating setpoint, and whether the control variable is laser diode

Grounding with modules and components: Some laser diode packages short either pin of the laser diode to the case, which may connect the pin to earth ground through system hardware. Leakage Current: Ideally, when a laser diode driver is turned off, no current flows through the diode. This is called Constant Power Mode. Input Impedance: This is specified for analog voltage inputs such as VSET or MOD IN.
