Abstract
To provide a laser device allowing the prevention of dew formation on a cooler of the laser device, while contributing to a longer lifetime of a humidity sensor to be used. A laser device includes a laser diode and a cooler for cooling the laser diode. The laser diode and the cooler are provided in a housing. The laser device includes: a humidity detector that detects humidity in the laser device while current is applied to the humidity detector; and a current application controller that controls the time of current application to the humidity detector. In one aspect of the laser device, the laser device further includes: a temperature detector that detects a temperature in the housing; and a dew point calculator that calculates a dew point based on the humidity detected by the humidity detector, and the temperature detected by the temperature detector. The current application controller controls the time of current application to the humidity detector based on the dew point calculated by the dew point calculator.
