Panasonic Develops High-Power Blue WBC Technology to Revolutionize DDL Applications on Microfabrication

Share

On January 29, 2020, Panasonic Corporation announced it has succeeded in demonstrating the world's highest brightness blue laser. This has been achieved by using the wavelength beam combining (WBC) technology [1] on a direct diode laser (DDL) to produce a high quality output beam [2]. With this technology, power scaling is enabled while maintaining the beam quality by simply increasing the number of laser sources. This demonstration opens the door to laser intensities that could be two orders of magnitude higher than conventional blue laser systems. This technology will contribute to the emerging microfabrication processes, whose demand is expected to grow in industrial applications, such as in the automotive industry.

The automotive industry is moving towards “electrification” and “miniaturization” while requiring “high rigidity,” “design flexibility” and “productivity.” Against this background, the anticipation for the microfabrication lasers that can process various kinds of materials such as copper, gold and plastic is building up. Especially, blue laser with a high optical absorption efficiency has a high demand in the field of copper fabrication for the automotive motors and batteries. Highly-productive processing requires a laser beam source that has both high output power and high beam quality.

In order to attain such a beam source, Panasonic started collaboration with TeraDiode, Inc. (TDI), a Massachusetts, U.S.-based company, in 2013, and since has been developing WBC technology which can combine multiple and different wavelengths into one combined beam. In 2014, Panasonic released LAPRISS; the world’s first laser welding robot system equipped with an infrared DDL using WBC technology*1. In 2017, the company acquired TDI as a wholly owned subsidiary*2 and started developing on the output-power optimization on WBC as well as shortening the wavelength.

The output power optimization of the high-beam-quality blue laser (wavelength band = 400 – 450nm) was realized by combining more than 100 emitters from multiple diode bars [3] with WBC technology.

This WBC technology combines the beams from multiple emitters at different wavelengths that are incident on the diffraction grating at angles corresponding to each wavelength. The resonator is then formed in between the shared partially-transparent mirror and each edge face of the emitters. As a result, the output beam has achieved a output of 135 W with a high beam quality of BPP [4] 1.5mm・mrad.

Going forward, Panasonic will develop a processing system that is equipped with this laser beam source, as well as the process optimization in laser processing.

Panasonic will hold exhibits and lecture sessions on our technical achievement at PHOTONICS WEST 2020 in San Francisco from February 1 to 6, 2020.*3

A part of this research and development includes the data obtained from a project – “Development of advanced laser processing with intelligence based on high-brightness and high-efficiency laser technologies (TACMI project)” – commissioned by the New Energy and Industrial Technology Development Organization (NEDO) of Japan.

[Applications] Laser processing (welding, cutting, etc.)

Glossary
[1] Wavelength Beam Combining (WBC) technology: The technology that combines the beams with different wavelengths that are emitted from the multiple DDLs (direct diode lasers) on a diffraction grating.

[2] Beam quality: An index indicates how easy it is to combine the beam. Higher beam quality has smaller diameter and highly collimate feature.

[3] Diode bar: A laser bar that has multiple emittance stripes (emitters) in an array configuration on a single semiconductor chip.

[4] BPP (Beam Parameter Products): This is defined as the product of the radius r0 of the beam waist at the focusing position multiplied by the half-value half-width θ of the beam divergence angle; BPP = r0xθ. The unit is expressed in [mm・mrad]. The smaller BPP is, the higher the beam quality becomes.

They walk away from the profession they were once extremely passionate about, partly because medical experts have been able to identify that they suffer from real trauma and severe stress. Others, like Minnesota based Special Education Assistant Erin Gonzales are keen to continue and state: “I work at a school where human bites are a daily occurrence, but I work with kids with special needs. But honestly, I wouldn’t trade it for the world.” Oklahoma based Psychiatric Nurse Practitioner Miranda Hagan shares her desire and refuses to give up: “I have permanent sca

Strengthening Position in the Smart Energy Space, Trilliant Acquires Quadlogic Multi-Tenant Panel and ANSI Socket-Based Metering Solutions26.2.2020 17:30:00 EETPress release

Trilliant Networks, a global provider of leading Smart Grid and Smart City solutions, announced that they have acquired rights to Quadlogic’s multi-tenant panel and ANSI-based metering for Canada and international markets. This acquisition enables Trilliant to augment their leadership position in providing custom-tailored and turn-key metering services and solutions to the Canadian and international marketplace. Multi-tenant metering measures the electricity use of individual suites in multi-occupant buildings including condos and facilitates accountability for each suite’s own costs. A benefit of converting from bulk or master-metered service to submetering services is that electricity consumption is measured at precise intervals with the ability to capture time-of-use data. “Quadlogic’s technology is the current industry standard metering platform for mixed use, commercial, and multi-residential applications, and is a perfect fit to support our growth strategy” said Steven Lupo, mana
