Description
Technical field
The invention belongs to technical field of semiconductors, particularly a kind of water-cool control method of avoiding the laser crystal dewfall.
Background technology
The high power all solid state laser is when starting, and the recirculated cooling water of water cooling unit is started working earlier, because the water cooling unit refrigeration rapidly; Laser crystal that is cooled and ambient temperature produce the bigger temperature difference at short notice, have under the air ambient of certain humidity, and steam on every side is dewfall on laser crystal easily; Thereby influencing laser vibrates in the chamber; Cause laser power to descend, when serious even damage laser crystal, cause the laser can't operate as normal.
Summary of the invention
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.
Wherein the input service state parameter comprises: laser works power and water cooling unit work water temperature.
