The objective of the invention is to, a kind of control coolant water temperature method of laser crystal dewfall when avoiding high power laser to open is provided.
The present invention provides a kind of water-cool control method of avoiding the laser crystal dewfall, comprises the steps:
Step 1: at first open the control water temperature system program;
Step 2: the control water temperature system program detects the initial temperature of temperature, humidity and the cooling water of air automatically, and deposits in the ambient condition parameter of program;
Step 3: input service state parameter in the control water temperature system program;
Step 4: operation control water temperature system program, output water temperature decline stage numerical control system signal;
Step 5: water cooling unit freezes stage by stage, to avoid laser crystal bar dewfall.
Wherein the ambient condition parameter comprises: the initial temperature of recirculated cooling water in the water cooling unit before the temperature of air, humidity and the laser system work.
