Laser Drying—— Rapid Local Evaporation for Industrial Processes
Laser drying is a process that uses controlled laser heating to rapidly evaporate moisture or solvents from targeted areas.
It enables fast, localized drying without heating the entire part or substrate.
- Rapid drying of thin films and coatings
- Local solvent evaporation in printing and coating processes
- Surface preparation before bonding or further processing
What Is Laser Drying?
Laser drying is a non-contact thermal process in which a laser delivers controlled energy to evaporate water or solvents from materials such as films, coatings, inks, or treated surfaces.
The process provides fast response, precise energy control, and selective drying without affecting surrounding areas.
Key characteristics:
- 非接触, 局所加熱
- Fast evaporation with precise control
- Minimal thermal impact on surrounding areas
Why Use Laser Drying Instead of Conventional Methods?
- Localized Heating — Only the target area is heated, avoiding unnecessary thermal exposure of the entire part.
- High Process Speed — Rapid energy delivery enables immediate evaporation and short cycle times.
- Clean & Contact-Free — No airflow disturbance, no mechanical contact, and minimal contamination risk.
How Laser Drying Works
A laser beam heats the surface layer of a material to a temperature sufficient for moisture or solvent evaporation.
Heat input is precisely controlled to avoid material damage, deformation, or unwanted chemical changes.
Key Characteristics
Fast heating and fast response
Shallow thermal penetration
Programmable power, スピード, and spot size
Why Diode Lasers for Drying Applications
Uniform Energy Distribution
Top-hat beam profiles enable controlled heating without overheating or hotspots.
Precise Thermal Control
Adjustable output enables drying without overheating or damaging materials.
Flexible Integration
Easily integrated into coating lines, printing systems, and automated production cells.
When to Choose Laser Drying
- When fast, localized drying is required
- When conventional ovens or hot air are too slow
- When surrounding materials must remain cool
- When drying must be integrated inline with production
