HT4000 - The HT4000 series of End Pumped Solid State Lasers are maintenance free, air-cooled diode-pumped lasers with very compact, small footprints, ideal for a wide range of metals, plastics and ceramics. By utilizing state-of-the-art photonics technology, the HT4000 laser sources have achieved a high optical excitation efficiency of 40-50%, with a low utility cost. These highly reliable lasers are available in direct end-pumped and fiber-coupled versions, and can even be fine-tuned by using different crystals to suit specific applications and materials. Our laser systems can be configured as a standalone system or for integration with other structures and handlers.ht4000 end-pumped laser marker
