AI Technical Summary
Existing semiconductor laser devices face challenges in accurately controlling the temperature of the semiconductor laser element due to measurement errors caused by heat transfer from pin terminals through electrically conductive wires to the temperature detection part.
The semiconductor laser device incorporates a heat capacity increasing part that contacts the wire connecting the temperature detecting element and the output terminal, thereby increasing the heat capacity of the wire and reducing heat transfer to the temperature detecting element.
This configuration allows for accurate detection of the semiconductor laser element's temperature, enabling highly accurate control of the semiconductor laser element's temperature and reducing wavenumber variation, which is particularly beneficial for optical analysis applications like infrared spectroscopic analysis.
