WAVETRONICS WT307C – Frequency-Stabilized He-Ne Laser Module | WT300 Series
Precision-grade stabilized helium-neon laser engineered for demanding metrology, interferometry, and OEM photonics applications. The WT307C carries dual cross-reference part numbers 0010-00138 and ENG1003, confirming full interchangeability across WAVETRONICS service documentation and third-party procurement databases.
Engineering Background: He-Ne lasers operating at 632.8 nm remain the gold standard for displacement measurement, holography, and wavelength calibration due to their exceptional coherence length and narrow linewidth. The WT307C adds an active frequency-stabilization loop that suppresses mode drift caused by thermal and mechanical perturbations, delivering output stability an order of magnitude beyond unstabilized tubes.
Product Positioning: Targeted at OEM instrument builders, university metrology labs, and industrial inspection system integrators who require a drop-in, calibration-traceable laser source with documented long-term frequency reproducibility.

System Architecture & Signal Flow
The WT307C integrates a sealed He-Ne plasma tube within a thermally managed housing. An internal photodetector samples a fraction of the output beam; the error signal drives a piezoelectric actuator on the cavity mirror to lock the lasing frequency to the center of the Doppler-broadened gain profile. The stabilized beam exits through an AR-coated output window. A separate power supply input (not included) provides the high-voltage discharge excitation and low-voltage servo electronics supply.

Technical FAQ
Q: Is the WT307C a direct replacement for 0010-00138?
A: Yes. WT307C, 0010-00138, and ENG1003 are all WAVETRONICS internal designations for the same stabilized He-Ne laser assembly.
Q: What power supply is required?
A: He-Ne lasers require a dedicated high-voltage ballast supply (typically 1,000–2,000 V ignition, 1,500–2,000 V sustain at 5–10 mA). Contact us for compatible WAVETRONICS PSU options.
Q: Can the output be fiber-coupled?
A: Yes. The TEM₀₀ beam couples efficiently into single-mode fiber (630 nm SM) using a standard aspheric coupler. Coupling efficiency >60% is routinely achieved.
Q: What is the warm-up time to reach specified frequency stability?
A: Typically 15–30 minutes from cold start for the thermal servo to reach steady state. Allow 60 minutes for highest-accuracy metrology applications.
Q: Do you offer calibration certificates?
A: Functional test reports are standard. NIST-traceable calibration certificates can be arranged through our partner calibration laboratory — please enquire at time of order.
