TECHNICAL FIELD
[0001] The present application relates to the field of laser technology, in particular to a laser pressure balancing device. BACKGROUND
[0002] Laser, as a kind of precision instrument with extremely high speed, outstanding precision, wide range and strong anti-light, electrical interference ability, plays a vital role in the field of modern science and technology. It is often carefully installed on the top of the vehicle or the outside of the submersible to perform high-precision measurement and data acquisition tasks. The choice of these installation positions aims to maximize the field of view range and operational flexibility of the laser, so as to ensure that accurate and reliable data can be obtained in various complex environments.
[0003] However, in the process of using the laser, the operation specification must be strictly followed, especially when facing extreme environmental conditions. For example, when the vehicle is traveling at an extremely fast speed, the airflow around it will form a high-pressure airflow, whose speed and power can be unimaginable. Similarly, in deep-sea exploration tasks, the water pressure borne by the submersible is also huge, far exceeding the pressure level in the conventional environment.
[0004] If the operator recklessly opens the protective end cover of the laser in these two extreme cases, the consequences will be disastrous. The high-speed airflow or high-pressure water flow will directly impact the internal precise optical elements and electronic components of the laser, and these fragile parts are almost unable to withstand such a huge external force impact without any protection. Therefore, it is likely to cause damage to the internal laser, including deformation of optical elements, short circuit of electronic components, etc., thereby seriously affecting the normal work and performance of the laser.
