Our laser diode collection has low- and high-power lasers, with low-operating currents, long lifespans, and efficiency, all while remaining 100% RoHS-compliant.

Interest grows in new 1.2 W red laser diodes, HL67203HD & HL69203HD, intended for skin treatment and photo-immunotherapy

Ushio Inc. announced sample shipments of the new HL67203HD and HL69203HD multi-mode laser diodes. These laser diodes offer output power (1.2 W) and efficiency (40% and 41%, respectively) improvements over conventional 675 nm and 690 nm red laser light sources that are in common usage for healthcare, medical, and life science applications.

The new red laser diodes, designed by Ushio’s engineers in Kyoto, carry out highly efficient and short-lived photochemical reactions with substances and reagents, found in the human body, which absorb light in the 670–690 nm wavelength range. The absorption at these wavelengths make Ushio’s red laser diodes an excellent choice for many medical and health applications, such as photodynamic therapy for cancer treatment, as well as acne or blemish treatment.

Furthermore, HL67203HD and HL69203HD have promise in practical life science analytics, such as Raman spectroscopy and confocal microscopy. In particular, high-power, high-efficiency, 690 nm red LDs coupled with fibre have seen an increased interest from the field of photo-immunotherapy, which has been attracting attention in recent years as a “fifth cancer treatment”.

Compact, efficient 200 mW laser diodes for life sciences, bio-medical & quantum applications

Ushio Inc. released samples of compact, high-power, high-efficiency single-mode laser diodes at wavelengths of 675 nm and 690 nm. While the 200 mW red lasers are expected to be used in an ever-growing list of applications, they are widely predicted to be a popular tool in research & development for life sciences, biomedical and quantum fields.

Wavelengths around 670 nm have a wide range of applications, including life science fields such as Raman spectroscopy and confocal microscopy, medical fields such as acne treatment and blemish treatment, as well as applications in quantum technology fields such as atomic laser cooling and quantum computers, where research & development has been active in recent years.

Wavelengths in the 690 nm band are also put to practical use in research & development of quantum-related fields, characterised by optical lattice clocks, and in the medical field, such as photo-dynamic therapy (PDT) and photo-immunotherapy for cancer.

Ushio’s experience enabled new red laser diodes to overcome an old “barrier”

Ushio applied the high-power, high-efficiency, high-reliability technologies cultivated through the development of its 640 nm and 660 nm band products in the development of the new 670–690 nm laser diodes. As a result, they are smaller, less complex, and less expensive than already established alternatives, such as diode-pumped solid-state (DPSS) laser modules. In addition, compared to semiconductor laser diode technologies, like DPSS, Ushio’s laser diodes possess a lower luminous efficiency, which was previously seen as a barrier to their widespread adoption.

With the shipment of these samples, Ushio will further expand its range of red laser diodes and contribute to the spread and improvement of the performance of red laser diode-equipped devices in a wider range of fields.

New high-efficiency, 200 mW laser diodes for levelling, shows, and measurement applications

Ushio Inc. announced a new high-power (200 mW), single-mode laser diode series. Emitting a wavelength of 639 nm, the HL63642DG series boasts improvements to efficiency and features low power consumption. Initial shipments of the HL63642DG series began in January 2022.

Thanks to their high visibility, red laser diodes with oscillation wavelengths between 630 nm and 640 nm are used in devices such as levellers, distance meters, laser projectors, and show lasers. Since 2018, Ushio saw great success in those markets with its 639 nm HL63392DG series, which also features an optical output power of 200 mW; however, customer feedback revealed a demand for continuous improvement in the characteristics and efficiency.

In the market for levellers and rangefinders, for instance, vigorous investment in housing and infrastructure has led to a demand for products that operate stably for longer periods in a wide range of outdoor temperatures.

In response, Ushio successfully reduced the threshold current and operating current by further optimizing the active layer structure and chip structure parameters, resulting in a significant improvement in wall plug efficiency. In addition, Ushio’s engineers extended the previous operating temperature range (-10°C to 60°C) to -40°C to 60°C. This not only reduces power consumption, downsizing, and extended battery life of devices using this product, but also expands the usable environment to extremely cold regions.

Intended applications for HL63641DG, HL63642DG & HL63643DG
  • Levellers & rangefinders
  • Measurement light source
  • Show Lasers
  • Medical Light Source
  • Laser Module
