Key Operating Parameters

FAQ

Q: What are the core advantages of VCSEL versus edge‑emitting laser diodes?A: VCSEL produces rotationally‑symmetrical beam output, simpler optical collimation, superior wavelength stability over temperature, and supports surface‑mount assembly for high‑volume manufacturing.

Q: Can this VCSEL run under continuous‑wave mode?A: This series is optimized for QCW or pulsed operation. Continuous‑wave driving beyond datasheet limits will cause chip overheating and permanent device damage.

Q: Do you provide samples for prototype validation?A: Yes. We offer sample units for lab testing before customers place large‑volume production orders.
