581.5nm Lasers Overview

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.

These high power, nanosecond 581.5nm lasers are available with either free-space or fiber-coupled output and a variety of pulse energies depending on the applications needs. Typical applications for these Yellow Lasers include Optogenetics and more.
