Used ESI 44 #149031 for sale

ESI 44 is a single frequency, frequency-doubled, CW Nd:YAG laser. It operates in the ultraviolet wavelengths with an output power of up to 25 Watts at a wavelength of 213.1 nm. It has a long coherence length, excellent beam quality and good stability. The laser uses the Kerr-Cell frequency-doubling technique, using a Brewster Angle crystal for the conversion to UV. The output beam is tightly collimated, producing a focused spot of <100 µm. The laser has a patented optical resonator design, which produces stable output power on demand. The laser is rugged, compact and low-maintenance. It has a light-weight, aluminum enclosure and is easy to install. It is equipped with a range of features such as remote monitoring and control, as well as an embedded diagnostic system. It has a laser head that allows easy integration with different optics, such as beam expanders and attenuators. Other features include built-in temperature regulation, an alarm system, adjustable pulse rate and duration, and a recycle time of 5-100 μs. 44 is an ideal choice for applications such as photogrammetry and lithography. It may also be used for material processing, inspection and preparation, medical diagnostics and treatments, and astrophysics and atmospheric science. Due to the long coherence length, it can be used to generate high-resolution images and is particularly suited for imaging in deep ultraviolet. ESI 44 has a range of safety features, including automatic shutoff in case of overheating. It is compliant with Laser Class 1 safety standards, meaning that it is safe to use with minimal protective eyewear. The laser is also fitted with interlocks and integrated safety systems to ensure the safety of operators. All in all, 44 is a reliable, high-quality, single-frequency laser that offers excellent performance at a cost-effective price. It is the perfect choice for applications in the UV wavelength range, offering superior stability and performance.
