Request InfoTOPTICA Photonics Inc.VICTOR, N.Y., Feb. 28, 2013 — Toptica Photonics Inc.’s TopMode diode lasers provide high-coherence mode-hop-free operation. At blue-violet wavelengths, they achieve high single-frequency output power while operating as easily as a HeNe laser. They feature a spectral width of <5 MHz and a coherence length >25 m. Proprietary CHARM (CoHerence-Advanced Regulation Method) technology actively stabilizes the lasers’ coherence and ensures continuous single-frequency operation. CHARM eliminates mode hops and prevents sudden step changes of the laser power or frequency, resulting in stability and enabling...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 11/3/2021OEM Laser Diode ModuleThe PM90(685-100) laser from Power Technology Inc. is a 685-nm, 100-mW laser diode module for OEM applications.

This article provides the basic information about how and why lasers work.Over 60 years have passed since the first demonstration of a laser in 1960. After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a problem,”...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...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.
