Frequently Asked Questions

What are the main applications of the 760 nm DBR Laser Diode?

The 760 nm DBR Laser Diode is widely used in applications such as oxygen (O₂) sensing, LiDAR, and remote sensing. Its single-frequency operation and high spectral purity make it ideal for precision measurements and scientific research.

What packaging options are available for this laser diode?

The 760 nm DBR Laser Diode is available in multiple packaging options, including Chip on Submount (CoS), TO-8, C-Mount, and Transmitter Optical Subassembly (TOSA). Additional free-space package add-ons such as Mode-Hop Free (MHF) and Virtual Point Source (VPS) Lens are also available.

How does temperature affect the wavelength of this DBR laser?

The laser exhibits a temperature tuning rate of approximately 0.06 nm/°C, meaning that its wavelength shifts slightly with temperature changes. For precise operation, temperature control using a Thermoelectric Cooler (TEC) is recommended.

What safety precautions should be taken when handling this laser?

This laser diode is sensitive to electrostatic discharge (ESD) and should be handled in an ESD-safe environment using grounded workstations and wrist straps. It should always be stored in an antistatic container with leads shorted together to prevent damage.

What is the side mode suppression ratio (SMSR) of this laser?

The 760 nm DBR Laser Diode has a high Side Mode Suppression Ratio (SMSR) of -40 dB, ensuring single-frequency operation with minimal interference from unwanted modes.
