4. Product Introduction
The JDSU (Lumentum) 2213-75TSLKTB is an air-cooled argon-ion laser head in a cylindrical package delivering 75 mW of TEM00 output. It is commonly configured for single-line operation near 488 nm and is used in industrial inspection, semiconductor wafer analysis (AIT systems), scientific instrumentation, and precision measurement applications.
The design provides stable beam pointing, low noise, and reliable long-term performance without water cooling. The head integrates with a compatible power supply and control electronics. New-surplus and tested units remain available for maintaining legacy optical systems where argon-ion sources are still required.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No laser output | Power supply or interlock open | ❌ Low | Verify supply voltage and interlock status | Check external power supply and safety interlocks first |
| Low or unstable power | Misaligned optics or aging tube | ✅ High | Measure output with calibrated power meter | Clean optics; verify current settings; replace if drifted |
| Excessive beam pointing drift | Thermal instability or mechanical stress | ✅ High | Monitor pointing after full warm-up | Allow full 15-min warm-up; check mounting rigidity |
| High noise or mode hopping | Incorrect current or temperature | ✅ Medium | Confirm operating current and cooling airflow | Adjust current; ensure unobstructed air intake/exhaust |
| Over-temperature shutdown | Blocked airflow or high ambient | ✅ Medium | Inspect fans/filters and ambient temperature | Clean air path; improve ventilation |
| Intermittent operation | Umbilical or connector issue | ✅ Low | Inspect cable and connectors for damage | Reseat or replace umbilical cable |
If the laser still fails to meet specification after these checks, record output power, beam profile, and operating hours, then contact technical support with photos of the installation.

6. Frequently Asked Questions (FAQ)
Q: What is the typical wavelength of the 2213-75TSLKTB?
A: Most units in this series operate at 488 nm (blue). Confirm the exact wavelength configuration for your specific head, as some variants support additional argon lines.
Q: Is water cooling required?
A: No. This is an air-cooled design. Ensure adequate airflow around the intake and exhaust ports.
Q: What power supply does it need?
A: A compatible JDSU/Lumentum argon-ion laser power supply matched to the 2213 series head. Do not operate the head without the proper supply and interlocks.
Q: What is the beam quality?
A: TEM00 mode purity greater than 95%, with beam diameter approximately 0.65 mm and divergence around 0.95 mrad.
Q: How long is the warm-up time?
A: Maximum warm-up time is 15 minutes to reach stable operation and specified pointing stability.
Q: Is this laser still in production?
A: The 2213 series is a legacy air-cooled argon-ion product. New-surplus and refurbished heads are the primary sources for replacement.
Q: What safety class is it?
A: CDRH Class IIIb. Appropriate laser safety eyewear, interlocks, and procedural controls are required.
