Abstract

A serious rust phenomenon has been observed in an enclosed laser cavity. To figure out the reason which induces the rust, some experiments were carried out by recording the variation of the temperature and relative humidity at different positions. Thus, the vapor density can be numerically deduced by using the measured physical features. To avoid the undesirable rust phenomena occurring again, the exchange windows were chiseled out on an inner cover of the enclosed laser cavity in order to decrease the difference between the vapor density inside the cover and that outside the cover, which relates to the efficiency of dehumidification. The results validate that such a difference of the vapor density is a function of the area of exchange windows. Then, the curves of the vapor density versus the area of exchange windows have been plotted. It has been demonstrated that adding the area of exchange windows, which were pasted by some particulate air filters to prevent external dust particles from entering, on an inner cover might be a feasible method to avoid rust near the water cooling elements. Such a study might be useful for laser technicians to pay much more attention to the protection of undesirable vapor-induced rusting.
