581.5nm Lasers

What are 581.5nm Lasers?

581.5nm Lasers, specifically Diode-Pumped Solid-State (DPSS) Lasers, utilize the second harmonic of Nd:YLF laser material at 1163nm. Given a particular laser, with a particular fundamental wavelength, second harmonic generation is less efficient and cannot achieve the same energy levels compared to its fundamental wavelength counterpart.

Q-SHIFT Series

Q-Shift SeriesThe Quantas-Q-SHIFT series is a family of Q-switched DPSS lasers featuring a built‑in nonlinear wavelength conversion stage, allowing the production of wavelengths that are not accessible with conventional solid-state laser sources, including 1163, 1177, 1300, 1317, 1551 and 1571nm. An optional harmonics generator is also available for for the Q-SHIFT, allowing generation of up to the 4th harmonic for each fundamental wavelength.
