D2-100 CECL Laser Module
- Narrow Fast Linewidth (<100 kHz)
- Vibration Immune: no moving parts or piezos
- Circular Collimated Laser Output
- Large and Fast Mode-Hop-Free Tuning via Injection Current
- Center Wavelength Custom Fixed to Your Specifications
Our chip external-cavity lasers (CECL) is a grating-feedback laser fabricated on a rigid monolithic substrate without any moving parts or piezos. Frequency tuning is via injection current and temperature. The short external cavity increases immunity to vibration and enables mode-hop-free tuning over 10 GHz ranges, enabling fast, tight locking to cavities or atomic and molecular transitions. CECLs combine the robust nature of DFB/DBR lasers with the low phase noise and wavelength flexibility of external cavity lasers. The center wavelength is custom fixed during manufacture. The module comes with two stages of TEC temperature control, and circularization optics.
