Ushio has expanded its portfolio of high-power laser diodes in the 630nm to 690nm red wavelength band, introducing five new wavelengths to the existing lineup of 1.2W laser diodes. This range is proving highly versatile in medical and healthcare applications, particularly in photodynamic therapy (PDT) and skin treatment.

In recent years, non-invasive light-based cancer therapies like PDT and photoimmunotherapy (PIT) have gained attention. These treatments necessitate lasers with specific wavelengths corresponding to the peak absorption wavelengths of photosensitizers. Examples include 635nm for 5-aminolevulinic acid (5-ALA), 664nm for sodium taraporphine in PDT and approximately 690nm for phthalocyanine compounds (IR700) in PIT. Red laser diodes with high watt-class power and seamless coupling to optical fibres are crucial for these light sources.

Ushio previously launched the HL65213HD 659nm 1.2W laser diode in 2019, followed by the HL67203HD 675nm and HL69203HD 690nm 1.2W laser diodes in 2022. Responding to market demands for expanded wavelength options, they have introduced five new wavelengths (630nm, 635nm, 652nm, 665nm, and 683nm), bringing the product lineup to a total of eight offerings.

Leveraging Ushio’s unique technologies in red wavelengths, these products boast 1.2W high power, 40% high wall plug efficiency and a remarkable 10,000 hours of operational life. Additionally, the emitter size is kept relatively small at 80μm width, enabling efficient coupling of laser beams to optical fibres. This not only contributes to downsizing but also ensures low power consumption and extended equipment life.

ABOUT Ushio
Ushio’s laser diode collection offers wavelengths across UV (375–405 nm), red (630–690 nm), and NIR (705–852 nm), with prospective optical output powers from 5 mW to 3,500 mW. Our LD collection has low and high power lasers, with low-operating currents, long lifespans, and efficiency, all while remaining 100% RoHS-compliant.

Ushio’s Epitex division has grown into the largest collection of light emitting diodes on the market. Covering all violet, visible, and infrared wavelengths, from 365 nanometres (nm) to 1,750 nm, this vast catalogue creates a one-stop-shop for single and multi-wavelength LEDs.
