Used ESI 44 #9158762 for sale

ESI 44 is a CW Oscillator laser designed for applications in spectroscopy, micromachining, and precision alignment. This single-mode laser, based on external cavity surface emitting diode technology, typically produces up to 6 mW of power at a wavelength of 442 nm. Featuring a highly stable and efficient design, 44 laser ensures excellent performance with a robust, long lifetime. ESI 44 uses an advanced gain medium that is formed by bonding two gain chips to each side of a silicon substrate. This gain medium is then protected by a process known as "Total Internal Reflection". This process ensures that all light is reflected inside the laser cavity and trapped until it is eventually emitted from the front of the laser. The precise design of the optical cavity and the highest quality control of the components guarantee that the laser's output is of single-mode operation, with diffraction-limited beam quality. The lasers operate with a long-lifetime currentless operation that does not require additional components, such as a cooling system, and can be easily integrated into other systems. The device is sealed and hermetically packaged to ensure its performance and also to protect it from environmental factors such as dust and humidity. 44 can operate with both temperature and current control while maintaining a normal operation and providing a long lifetime. Its compact, lightweight design coupled with its simple electrical connections make this laser ideal for operation in both laboratory settings and in production-level systems. Due to its reliable output strength, ESI 44 laser is frequently used in industrial applications where superior precision and accuracy is required. 44 is also well-suited for fiber-optic applications as its output characteristics provide excellent beam pointing stability with minimal spectral linewidth. Overall, ESI 44 laser is an excellent choice for applications that require a long-life, stable laser solution at an affordable price. With its superior performance, ease of use, and reliable output, 44 is often a trusted and valuable toolal used for scientific and industrial projects.
