Nd:YAG laser - Definition, Construction and Working
WEBNd: YAG laser is a four-level laser system, which means that the four energy levels are involved in laser action. These lasers operate in both pulsed and continuous mode. Nd: YAG laser generates laser light commonly in the near-infrared region of the spectrum at 1064 nanometers (nm).
Nd:YAG laser - Wikipedia
WEBThe high-intensity pulses may be efficiently frequency doubled to generate laser light at 532 nm, or higher harmonics at 355, 266 and 213 nm. Nd:YAG absorbs mostly in the bands between 730–760 nm and 790–820 nm. [3]
YAG Lasers – Nd:YAG laser, Yb:YAG, yttrium aluminum garnet
WEBLumibird nanosecond Q-switched Nd:YAG lasers are well known for their ruggedness and versatility. From 5 mJ to 2.3 J at 1064 nm, from single pulse to 400 Hz, they can be diode-pumped (compactness, ease of use) or flashlamp-pumped (high energy), and are available at 532 nm, 355 nm, 266 nm and 1.5 µm.
