1. A light detecting device comprising:
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 configured to control the pump, wherein
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.
