1. A probe system, comprising: a base configured to be fastened on the cockpit of an aircraft;a plurality of regularly spaced static pressure taps arranged through the base and configured to be connected to a pressure measurement device;at least one optical window transparent to laser radiation and inserted into the base; anda fastener configured to fasten the optical window on the base,wherein the fastener comprises a retaining flange for retaining the optical window on the probe system and members for fastening the retaining flange on the probe system. 2. The system according to claim 1, wherein the optical window has an outer face flush with an outer surface of the base. 3. The system according to claim 1, wherein the optical window comprises a porthole formed of glass transparent to infrared radiation. 4. The system according to claim 3, wherein the optical window comprises a seal inserted between the base and the porthole, and wherein the seal is formed of a material with a thermal expansion coefficient lower than the thermal expansion coefficient of the material of the base. 5. The system according to claim 3, wherein the optical window comprises an insert secured to the base and in which the porthole is received, and wherein the difference between the thermal expansion coefficient of the insert and that of the porthole below 100%. 6. The system according to claim 3, wherein the base defines an orifice configured to receive the optical window, and wherein the porthole is maintained by mechanical engagement in the receiving orifice. 7. The system according to claim 1, wherein the optical window is integral with the base. 8. The system according to claim 7, wherein the base is formed entirely from a material transparent to laser radiation. 9. The system according to claim 3, wherein the porthole has a diameter between about 1 cm and about 6 cm. 10. A mixed primary reference probe for an aircraft, comprising: at least one probe system comprising at least one optical window;an optical head connected to a laser anemometer and arranged across from the optical window of the probe system; anda pressure measuring device,wherein the probe system further comprises: a base configured to be fastened on the cockpit of the aircraft; anda plurality of regularly spaced static pressure taps arranged through the base and connected to the pressure measurement device; anda fastener configured to fasten the optical window on the base,wherein the fastener comprises a retaining flange for retaining the optical window on the probe system and members for fastening the retaining flange on the probe system, andwherein the optical window is transparent to laser radiation and inserted into the base. 11. An aircraft, comprising: at least one mixed primary reference probe, the mixed primary reference probe comprising: at least one probe system comprising at least one optical window;an optical head connected to a laser anemometer and arranged across from the optical window of the probe system; anda pressure measuring device,wherein the probe system further comprises: a base configured to be fastened on the cockpit of the aircraft;a plurality of regularly spaced static pressure taps arranged through the base and connected to the pressure measurement device; anda fastener configured to fasten the optical window on the base,wherein the fastener comprises a retaining flange for retaining the optical window on the probe system and members for fastening the retaining flange on the probe system, andwherein the optical window is transparent to laser radiation and inserted into the base. 12. A method of measuring a plurality of physical properties relative to an aircraft, the method comprising: providing a primary mixed reference probe on the cockpit of the aircraft, wherein the mixed primary reference probe comprises: i) at least one probe system comprising at least one optical window, ii) an optical head connected to a laser anemometer and arranged across from the optical window of the probe system, and iii) a pressure measuring device, wherein the pressure measuring device comprises: i) a base configured to be fastened on the cockpit of the aircraft, ii) a plurality of regularly spaced static pressure taps arranged through the base and connected to the pressure measurement device, and iii) a fastener configured to fasten the optical window on the base, wherein the fastener comprises a retaining flange for retaining the optical window on the probe system and members for fastening the retaining flange on the probe system, and wherein the optical window is transparent to laser radiation and inserted into the base,sending/receiving laser radiation from the inside of the aircraft to the outside of the aircraft through the optical window via the laser anemometer optical head attached to the probe system to measure a speed of the aircraft, andmeasuring a static pressure near the aircraft via the static pressure taps of the or each probe system.
