Abstract
A light detecting device includes: a light detector; a heat exchanger thermally connected to the light detector; a coolant flow channel configured to be connected to the heat exchanger and allow a coolant for cooling the light detector to flow; a pump configured to cause the coolant to flow in the coolant flow channel; and a control unit that controls the pump. The control unit performs control such that a first drive power is supplied to the pump during a detection period in which the light detector performs light detection, and a second drive power is supplied to the pump during a standby period in which the light detector stands by without performing light detection, and the first drive power is smaller than the second drive power.
