How to Choose a 905 nm Pulsed Laser Chip: Seven Key Parameters and the Multi-Junction Power Ladder
Choosing a 905 nm emitter chip comes down to matching seven core parameters to your system's optics and electronics, then selecting a triple-, quad-, or six-junction power tier that balances target range against driver complexity.
How to Choose an Automotive LiDAR Emitter 905 nm vs. 1550 nm
Automotive LiDAR transmitters divide into two camps: 905 nm, which offers a mature supply chain, low chip cost, and direct silicon detector compatibility; and 1550 nm, which allows higher eye-safe optical power at the cost of pricier components and greater architectural complexity. Because each suits different range, budget, and volume needs, defining four key parameters—target detection range, power and thermal budget, unit cost ceiling, and annual production volume—will naturally determine the right wavelength.

How Effective Is 1940 nm Laser Treatment for Varicose Veins
The 1940 nm wavelength is attracting interest in endovenous laser treatment (EVLT) because of its strong absorption by water. This supports localized energy deposition and treatment at relatively low power. Clinical studies have reported high vein closure rates and favorable recovery outcomes, although results depend on the device, fiber, treatment protocol, and patient selection.
GK Semiconductor provides proprietary laser chips, fiber-coupled modules, and complete system development support to help medical device manufacturers develop 1940 nm EVLT platforms.
