Used ESI 44 #9277560 for sale

ESI 44 is a Laser Amplification Equipment designed to provide a continuous wave, high-propellant pulse rate laser with a longer pulse duration than standard end-pumped solid-state lasers. 44 utilizes a flash lamp-pumped Nd:YAG crystal in a two-stage amplifier design to achieve a 50 watt generated output of eye-safe radiation. This laser system is ideally suited for applications such as long-range communication and secure optical back-up links. The active elements inside ESI 44 are a flash lamp-pumped active medium, Raman crystal, and secondary active medium. The flash lamp-pumped medium is an Ytterbium-doped crystal that provides a gain per pass. The Raman crystal is a carefully designed combination of potassium chloride (KCl) and erbium chloride (ErCl3). This special combination increases the gain of 44 unit. Lastly, the secondary active medium is a YAG crystal which amplifies the output pulse to 50 watts. ESI 44 laser machine features a high power beam-shaping optics train to provide a uniform beam with nearly perfectly circular cross-section and consistent power output across the useful emitting size. This beam-shaping optics train provides users with accurate aiming capabilities when used in communication and tracking applications. 44 is further equipped with active power control and cooling capabilities allowing it to operate without the risk of energy damage to its optics components (including the flash lamp, Raman crystal, and secondary active medium). The cooling tool of ESI 44 minimizes thermal distortion of the laser beam, allowing for maximum power efficiency. 44 also offers a wide operating temperature range, with an operating temperature of -4 C to 40 C. Close attention to detail has been taken to ensure reliable and stable operation over the expected operational lifecycle of the laser. This includes a number of detailed design and operational parameters, such as the use of a sophisticated ignition asset to ensure that the flash lamp is always ignited evenly, as well as temperature monitoring systems to ensure temperature stability of the laser throughout its operation. In conclusion, ESI 44 offers users a powerful, eye-safe laser with excellent beam-shaping optics and cooling capabilities, ideal for long-range communication and secure optical back-up links. This laser model is reliable, stable, and requires minimal maintenance, making it an ideal choice for many users.
