Daily maintenance checklist for a pulsed fiber laser?

# Daily Maintenance Checklist for Pulsed Fiber Laser Great question! Proper daily maintenance keeps your laser running safely and efficiently. Here's a professional checklist: ## 🔍 **Visual Inspections** - **Optics**: Check protective window and focusing lens for contamination, scratches, or burn marks - **Beam path**: Ensure mirrors and reflective surfaces are clean and properly aligned - **Cables**: Inspect fiber cable for kinks, bends, or damage (minimum bend radius typically 30cm) - **Enclosure**: Verify all safety interlocks are functional and panels are secure ## 🌡️ **System Checks** - **Cooling system**: Confirm chiller temperature is within spec (typically 20-25°C), check coolant level and flow indicators - **Fume extraction**: Test airflow; clean or replace filters if pressure drop is high - **Compressed air**: Verify pressure is adequate (typically 0.5-0.8 MPa), drain moisture from tanks - **Grounding**: Check earth connection is intact ## 🧼 **Cleaning** - **Protective window**: Clean with lint-free cloth and isopropanol (never touch with bare fingers) - **Work area**: Remove debris and metal dust from the work surface - **Nozzle**: Inspect and clean gas/air assist nozzle if applicable ## 📊 **Operational Test** - Run a **test pattern** on scrap material to verify beam quality and settings consistency - Check for unusual sounds, vibrations, or error messages - Log any anomalies in your maintenance record ## ⚠️ **Safety Verification** - Confirm emergency stop button functions properly - Verify laser safety glasses (OD-rated for your wavelength) are available and undamaged - Check warning signs and perimeter barriers are in place ## 📝 **Documentation** - Record operating hours, any issues observed, and corrective actions taken --- **Pro tip**: Schedule weekly deep-cleans of optics and monthly calibration checks. If you notice power degradation or beam quality issues, contact your manufacturer's technical support immediately. What type of pulsed fiber laser are you maintaining?
