Note:
(1)operating power shows kinks approx. every 10mA - 100mA in defined power range due to single longitudinal laser mode hoping
(2)FWHM is valid in the current regime free of mode hoping. Smallest and stable line width over time is only achieved with drift and noise free laser diode driver and temperature controller meaning current drift below 0.1mA and noise band <10 µA up to 10 MHz as well as internal temperature drift below 0.2°C.
