Buying Semiconductor Lasers
Semiconductor lasers encompass various types, with laser diodes being the most common. Additionally, there are optically pumped surface-emitting lasers (VECSELs) and quantum cascade lasers, each offering unique advantages for specific applications. These lasers are integral to modern photonics, providing high efficiency and versatility for communications, sensing, and industrial processes.
