(1) Typical values, sample tested. Depends on pulse width and selected power
(2) Depends on wavelength version
(3) All inputs have 10 kΩ pull-up resistors. Open input is equivalent to logic 'high'.
(4) Depends on ambient temperature. Cooling current changes due to temperature regulation of laser diode. (5) Operation below 15 °C may result in extended warm-up time.
