Request InfoCoherent Inc.Coherent Inc. has introduced a high-power 640-nm red diode laser module for use in flow cytometry and drug discovery. The single-emitter-based turnkey Cube 640-100 produces 100 mW of continuous-wave output in a 1-mm-diameter beam with M2 <1.5. The company says that the laser delivers a higher scan rate and a better signal-to-noise ratio than HeNe models. Maximum output wavelength is 644 nm, ensuring high transmission through the laser emission bandpass filters used in cytometry instruments and good blocking by commonly used detector filters.

Of all the solid-state laser crystals, it has stood the test of time best. Its high gain, narrow linewidth, low threshold and physical properties make it a most versatile laser material for a variety of applications.The ubiquitous Nd:YAG laser has played many roles over the years. For the military, it has provided rangefinding and target designation capabilities. When used with nonlinear optics or as a pump...Photonics HandbookFiber Lasers: New Types and Features Expand Applications: Since its inception, the fiber laser has attracted users because of its large gain and the ability to produce continuous lasing. The quasi-continuous wave for industrial applications further broadens fiber lasers’ appeal.The modern fiber laser is pumped by high-power, multimode single-emitter diodes or diode bars, typically through a cladding surrounding a single-mode core. This single-mode core is typically 5 to 12...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
