392nm Lasers, specifically Diode-Pumped Solid-State (DPSS) Lasers, utilize the third harmonic of Nd:YAG laser material at 1177nm. Given a particular laser, with a particular fundamental wavelength, fourth harmonic generation is less efficient and cannot achieve the same energy levels compared to its lower-order harmonic counterparts.
The Q-SHIFT series of Q-switched DPSS lasers is designed for researchers and application specialists working in micromachining, dermatology, LIDAR, time-resolved laser spectroscopy, and LIBS applications. With its built-in nonlinear wavelength conversion stage, this series allows the production of unconventional fundamental DPSS wavelengths, including 1163, 1177, 1300, 1317, 1551 and 1571 nm options, making it an ideal choice for those seeking wavelengths that are not accessible with conventional solid-state laser sources. With the optional harmonics generator, it is possible to generate up to the 4th harmonic for each fundamental wavelength, providing even more versatility.
