Nuvoton's Groundbreaking Indigo Semiconductor Laser

On June 12, 2025, Nuvoton Technology Corporation Japan (NTCJ) made headlines with its announcement of a revolutionary indigo semiconductor laser, aimed at providing alternative light sources to traditional mercury lamps. This innovation will be exhibited at the upcoming LASER World of PHOTONICS 2025, scheduled from June 24 to June 27 in Munich, Germany, where the company invites all visitors to its booth.

Key Features of the Indigo Semiconductor Laser

The new indigo semiconductor laser boasts an impressive optical output power of 1.7 W, emitting light at a wavelength of 420 nm. This wavelength is particularly close to the g line of mercury lamps, offering a significant advantage in providing effective alternatives. Notably, the laser comes in a compact CAN TO-56 package, making it easier to integrate into smaller devices compared to bulky mercury lamps.

NTCJ's expertise extends over 40 years of experience, having supplied more than 3 billion semiconductor lasers for optical disks. This extensive background supports the design and production of lasers that meet market needs efficiently. The new indigo laser features patented optical designs and heat dissipation technologies that enhance both efficiency and long-term reliability. By using this semiconductor laser, users can reduce energy consumption and the frequency of light source replacements, significantly lowering operational costs.

Compatibility and Flexibility

In addition to its primary capabilities, the indigo laser can be seamlessly combined with NTCJ’s mass-produced ultraviolet (378 nm) and violet (402 nm) semiconductor lasers. This combination allows the indigo laser to serve as an alternative light source for the i line (365 nm), h line (405 nm), and g line (436 nm) ranges typically covered by mercury lamps. Furthermore, by adjusting the output power ratio of each laser according to specific applications, designers can achieve optical configurations that were not feasible with conventional mercury lamps.

Looking Towards the Future

The introduction of NTCJ’s indigo semiconductor laser at LASER World of PHOTONICS 2025 exemplifies the company's commitment to innovation and sustainability. By providing alternatives to mercury lamps, Nuvoton is not just addressing market demands but is also aligning with global efforts for greener technology solutions.
