In the previous case about the application of CWUL-10 water chiller, 
we've mentioned that bubbles in the cooling water of water chiller will 
affect the precision laser. Then what kind of influence would it be? 
Firstly, we need to understand how bubbles in the cooling water can be 
formed. Generally the formation of bubbles results from the improper 
design of pipeline inside the water chiller. 
Please allow me to make a brief analysis on the influence of bubble formation on the precision laser: 
1.As heat cannot be absorbed by bubbles in the pipe, it would lead to 
the uneven heat absorption by water and thus cause the improper heat 
dissipation of the equipment. Then heat will be accumulated in the 
equipment during the operation, and the severe impact force generated 
when bubbles are flowing in the pipe will cause cavitation erosion and 
vibration on the internal pipe. In this case, when laser crystal 
operates under strong vibration condition, it will lead to crystal 
faults and more light extraction optical loss to shorten the service 
life of the laser. 
2.The continuous impact force imposed by something like medium material 
that has been formed by bubbles on the laser system will bring about 
oscillation to some extent, which would consequently give rise to a 
hidden danger to the laser. Moreover, the UV, green and fiber lasers 
have strict requirements on water cooling. As the service life of the 
embedded chip is closely related to the water pressure stability of the 
circulating cooling water, the oscillation caused by bubbles will 
significantly reduce the service life of the laser.    
Warm tips about S&A water chiller: The correct start-up sequence for
 the operation of laser with water chiller: Firstly, turn on the water 
chiller and then activate the laser. This is because that if laser is 
activated before the start-up of the water chiller, the operating 
temperature (It's 25-27℃ for ordinary lasers) might not be achieved 
immediately when the water chiller is started up and this will certainly
 affect the laser.   
For the cooling of precision laser, please choose S&A CWUL-10 water 
chiller. With a reasonable piping design, it can significantly prevent 
the formation of bubbles to stabilize the light extracting rate of laser
 and extend the service life. Therefore it can facilitate the users to 
save the cost.
