II-VI Suwtech launching high-power low-noise and high-power fiber-coupled green diode lasers

In hall B1 (booth 403) at Laser World of Photonics 2015 in Munich, Germany (22-25 June), II-VI Suwtech of Shanghai, China – a subsidiary of engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA – is introducing two new product lines: a high-power low-noise (HPLN) laser and a high-power fiber-coupled (HPFC) laser.

Both HPLN and HPFC lasers have been developed from II-VI Suwtech's high-power green diode laser (GDL). HPLN lasers realize less than 0.5% RMS noise at output power higher than 100mW. HPFC lasers achieve high output power up to 300mW with high polarization stability in single-mode (SM), multiple-mode (MM) and polarized-mode (PM) fibers.

In 2014, II-VI Suwtech developed a patented micro-chip design (patent approved) for its green diode laser that successfully lowers noise at high output power. The HPLN – with its high power stability, high reliability, good beam quality and high PER (polarization extinction ratio) – has wide applications in life science, laser display and machine vision.

II-VI Suwtech developed high-power fiber-coupled (HPFC) lasers from its green laser with high coupling efficiency. The new technology enables laser beam output from fiber with what is claimed to be exceptional polarization stability (PER>17dB), long-term reliability, and high coupling efficiency. Based on this technology, II-VI Suwtech has launched compact, cost-efficient fiber-coupled high-power lasers up to 300mW in various types of fiber: single-mode, multiple-mode and polarization-mode. The HPFC laser has broad applications in bioscience and analytical instruments, says the firm.
