Coherent Launches Best-In-Class 18 W 880 nm Single-Emitter Laser Diode For High-Performance DPSS Systems
Delivering 18 W optical output power with over 62% conversion efficiency and 97% polarization extinction ratio, the SES18-880A-190-10 sets a new benchmark for DPSS pump lasers in terms of performance, reliability, and cost-effectiveness. With a 190 µm emitter and one of the most competitive $/W ratios available in the 880 nm class, this product is ideal for precision applications requiring excellent beam quality and scalable power.
'The DPSS laser market is evolving rapidly, with demand growing in micromachining, advanced packaging, and semiconductor processing,' said Dr. Karlheinz Gulden, Senior Vice President, Laser Components and Subsystems at Coherent. 'This new diode allows customers to realize the full benefits of 880 nm pumping—delivering lower quantum defects, reduced thermal lensing, and enhanced mode quality compared to traditional 808 nm solutions.'
Built on the 6-inch GaAs wafer platform from Coherent, the SES18-880A-190-10 benefits from fully vertically integrated manufacturing—from epitaxial wafer growth to chip design and sub mount packaging. Its advanced chip architecture ensures consistent performance, high polarization purity, and robust thermal management, making it a standout option for end-pumped DPSS systems. Its wavelength range (870–876 nm) and optimized front facet reflectivity are engineered for compatibility with Volume Bragg Grating (VBG) stabilization, offering precise wavelength control and alignment flexibility.
Variations of the product are available at 878, 885, and 888 nm to support different DPSS gain media. Coherent also offers fiber-coupled modules using the same chip technology, supporting a wide range of integration needs. These modules, including the FACTOR series, provide scalable, high-efficiency pumping for advanced laser systems.
The SES18-880A-190-10 is generally available.

B&G Foods Announces Credit Agreement Amendment
BUSINESS WIRE)--B&G Foods, Inc. (NYSE: BGS) announced today that it has completed an amendment to its senior secured credit facility. The amendment temporarily increases the maximum consolidated leverage ratio permitted under its revolving credit facility, decreases the size of its revolving credit facility and modifies certain other terms and conditions. B&G Foods' maximum consolidated leverage ratio (defined as the ratio, determined on a pro forma basis, of consolidated net debt, as of the last day of any period of four consecutive fiscal quarters to adjusted EBITDA (as defined in the credit agreement) before share-based compensation for such period), will increase from 7.00 to 1.00 to 7.50 to 1.00 for the quarter ending June 28, 2025 through the quarter ending October 3, 2026 and then the maximum consolidated leverage ratio will decrease to 7.25 to 1.00 for the quarter ending January 2, 2027 before returning to 7.00 to 1.00 for the quarters ending April 3, 2027 and thereafter. The size of B&G Foods' revolving credit facility will decrease from $475.0 million to $430.0 million. In addition, for so long as the revolving credit facility is outstanding, the available amount (as defined in the credit agreement) of B&G Foods' cash that may be used for restricted debt payments and investments will be further restricted to a maximum consolidated leverage ratio of less than or equal to 7.00 to 1.00 after giving effect to such repayment or investment (measured on the date of irrevocable redemption notice so long as payment is made within 90 days) and for restricted payments, including dividends, to a maximum consolidated leverage ratio of less than or equal to 7.25 to 1.00 after giving effect to the restricted payment (measured on the dividend declaration date so long as payment is made within 90 days). As of June 28, 2025, the last day of B&G Foods' second quarter of 2025, $235.0 million aggregate principal amount of revolving credit loans remained outstanding. B&G Foods also announced that during the second quarter of 2025, B&G Foods has repurchased $20.7 million aggregate principal amount of B&G Foods' 5.25% senior notes due 2027 in open market purchases at an average discounted repurchase price of 89.98% of such principal amount plus accrued and unpaid interest. As of June 28, 2025, $529.3 million aggregate principal amount of the 5.25% senior notes due 2027 remained outstanding. 'We believe that temporarily increasing our maximum consolidated leverage ratio is a prudent measure given the current difficult consumer environment in the packaged foods industry, our working capital needs and tariff uncertainty. As evidenced by our recently announced divestiture of the Don Pepino and Sclafani brands and our repurchases of senior notes due 2027, we continue our efforts to reshape our portfolio through the divestiture of non-core brands and reduce long-term debt. We are also committed to reducing costs,' explained Bruce C. Wacha, Executive Vice President of Finance and Chief Financial Officer of B&G Foods. About B&G Foods, Inc.
