Frequently Asked Questions
This laser diode is Spectroscopy Certified, ensuring it operates within the K D2 transition range (±10°C from room temperature). Its single-frequency output and narrow linewidth (500 kHz) provide high spectral purity, making it ideal for potassium-based atomic spectroscopy.
The 766.700 nm DBR Laser Diode is available in Chip on Submount (CoS), TO-8, C-Mount, and TOSA packages. Additional options such as Mode-Hop Free (MHF) and Virtual Point Source (VPS) lens configurations can be added for enhanced performance.
The wavelength shifts at a rate of 0.06 nm/°C, allowing fine-tuning through temperature adjustments. The recommended operating temperature for the case is 5°C to 70°C, while the laser chip operates best between 5°C and 45°C.
The diode is highly sensitive to Electrostatic Discharge (ESD). When handling, use a grounded workstation and wrist strap. It should be stored in an antistatic container with all leads shorted together to prevent damage.
Yes, the laser wavelength shifts at a rate of 0.002 nm/mA, enabling precise wavelength tuning through current control. However, operating within the recommended current range (max 200 mA) ensures stable performance and longevity.
