The invention relates to double-wavelength blue-and-green intelligent laser evidence obtaining equipment which comprises a host machine, a probe and a connecting line. The probe is connected with the host machine through the connecting line. The host machine comprises a housing, a handle which is arranged above the housing, a display interface, a first input device, a safe locking device and a data storage interface. The double-wavelength blue-and-green intelligent laser evidence obtaining equipment perform real-time communication between equipment and a background terminal through a wireless communication module, thereby ensuring real-time field monitoring by personnel. Through a laser control module, a laser emitting head can be made to emit laser with different wavelengths, different powers and different light spot sizes, thereby improving evidence obtaining efficiency in an evidence obtaining field and improving reliability of evidence obtaining equipment, wherein in an output power adjusting circuit, a first diode, a second diode and a third resistor are used for adjusting output power of an output end. Furthermore the output power is larger than 10W, thereby improving reliability and practicability in outputting laser by the laser evidence obtaining equipment.
