Pump Laser Diodes Deliver High Power for Leading-Edge Applications (Laser Focus World)

In addition to its long life and small size, the laser diode (LD) has the highest wall-plug efficiency of any laser source known. As such, it provides much of the foundation for modern laser technology, and does this in two ways. First, LDs provide light at wavelengths from the UV to the mid-IR for many purposes. Second, LDs are extremely able pump sources for many types of optically pumped solid-state lasers, ranging from scientific to industrial, and ultrafast to continuous-wave (CW), as well as for a non-solid-state high-power laser, the diode-pumped alkali metal vapor laser (DPAL).
