Laser Diode Module

-
Image
The IQ1C250(473-300) laser from Power Technology Inc. is an instrument quality laser diode module for high-end OEM applications.  The IQ1C250(473-300)is available with digital or analog modulations. The new module offers 3 times the previously available power in this wavelength with 300 mW.  The IQ1C250(473-300) features a collimated beam with diffraction limited technology, provides a typical wavelength of 473 nm compared to the 488 nm by previous generation models and operates optimally from 8 VDC rather than 12 VDC. The versatility of the module makes it ideal for a range of uses including bioanalysis, fluorescence and Raman spectroscopy.  source:https://www.photonics.com/Product.aspx?PID=6&VID=146&IID=979&PRID=61945 www.civillaser.com

The largest consumer market for lasers in the world - China China's laser industry market started late,However, with the rapid development of China's equipment manufacturing industry, China's laser industry has achieved rapid development in recent years. China is an active market for manufacturing and industrial laser equipment. Affected by factors such as macroeconomic development, upgrading of manufacturing industries, and support of national policies, China's industrial laser industry has become one of the industries that are highly concerned, and the market is developing rapidly. In 2015, China replaced Europe and became the largest consumer market for lasers for the first time. In 2018 The market grew to around US$2.8 billion, accounting for 29% of the global market.

Femtosecond lasers extend glass cleaving to mixed materials

-
Filamentation cutting is a relatively new process that uses ultrashort-pulse (USP) lasers to cut a wide range of glass substrates, from soft borosilicates to chemically hardened glass used in smartphone displays. Among the advantages of filamentation cutting are the ability to produce curved shapes and cut-outs, cutting speeds up to 2000 mm/s, and superior stress-free edge quality, which eliminates the need for post-processing. The high peak intensity created by a focused USP laser produces self-focusing of the beam because of the nonlinear optical Kerr effect, further increasing power density until, at a certain threshold, a low density plasma is created in the material. This plasma lowers the material refractive index in the center of the beam path and causes the beam to defocus. If the beam focusing optics are properly configured, this focusing/defocusing effect can be balanced to periodically repeat and form a stable filament, which extends over several millimeters in depth throu...
