Sources for 266nm Light
Nd:YAG Laser: The initial source is a Nd:YAG laser, emitting light at a wavelength of 1064nm.
First Harmonic Generation (SHG): The 1064nm light is frequency-doubled to 532nm using lithium iodate.
Second Harmonic Generation (SHG): The 532nm light is then frequency-doubled again to 266nm using ammonium dihydrogen phosphate (ADP).
This multi-stage frequency doubling process allows for the generation of high-power, high-repetition-rate coherent ultraviolet light at 266nm. -
Application of 266nm Light
Laser ablation: The high energy of 266nm light can be used to remove material from surfaces with precision.
Spectroscopy: The strong absorption of 266nm light by certain molecules can be used to identify and quantify their presence.
Sterilization: The ability of 266nm light to damage DNA can be used to sterilize surfaces and materials.
