Here. the development and testing of a portable double peak pulse laser induced plasma spectroscopy (DPP-LIPS) based on passively Q-switched Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser excitation is reported. The latter delivered structured laser pulses at a repetition rate of up to 20 Hz. including two energy peaks of about 100 mJ each with a relative temporal spacing of a... https://www.joesjeanes.shop/product-category/solid/
