Key Conference 200612 – 13 November 2006 Telecom-grade Diode Lasers for Industrial Laser Applications

Toby Strite

Manager of High Power Laser Marketing


  • Evolution of Industrial Diode Lasers

    • Telecom-grade and beyond

  • Diode/Fiber-based Industrial Lasers

Fiber coupled industrial diode laser eras
Fiber-coupled Industrial Diode Laser Eras

  • Reliability (inception  2003) “$$$’s and *#&%^!!”

    • DPSS is considered technology of the future (“always has been, always will be…”)

    • Diode laser investment focused in telecom

    • Unreliable, low brightness bars are only choice

  • Telecom-grade (2003  ?) “$/Watt”

    • Telecom migrants disrupt brightness, drive $/Watt

    • Even low-end bars reliably deliver 10,000hrs

    • Reliability and $/Watts begin to de-couple

What is a telecom grade diode laser
What is a Telecom-Grade Diode Laser?

  • Operational Excellence and Business Breadth

    • Large, fully-absorbed fab (ISO-9001 a decade ago, now TL-9000)

    • High-volume off-shore assembly

  • Technical and Cost Roadmaps, Extensive Track Record

    • Platforms, not just products

  • Predictable, sustained performance

    • Rigorous NPI, PCN and PDN processes

    • Reliability understanding surpasses the qualification report

  • … Confidence and Transparency for the Customer!

Telecom 980nm pump lasers since 1993
Telecom 980nm pump lasers since 1993…

  • 90mW 980nm pumps assembled in Boston sold for $7000

  • Five chips, several packages, one transfer to China later…

    • 500mW 980nm pumps sell well below $1000

    • 90mW 980nm pumps cost $300

    • and 980nm pump vendors are (again) profitable

  • Over 13yrs, innovation and focused cost-reduction realized

    • 21% annual price reduction for 90mW part

    • 15% annual power increase for 980nm pumps

    • 26% annual $/mW price reduction to the market

The story moves to fiber laser pumps
The Story Moves to Fiber Laser Pumps

14% average annual

power increase

Annual 17.5% (red) power increases enabling 26% annual $/Watt erosion predicts a reliable 35W fiber-coupled diode will sell for $70 in 2016…!!

Third industrial diode era efficiency
Third Industrial Diode Era - Efficiency

  • Diode Efficiency (2005  ?) “still $/Watt”

    • reliable power is limited by waste heat

  • For diodes to progress, efficiency must increase

32 Watts

Optimizing single emitter efficiency
Optimizing single-emitter efficiency

Research funded by DARPA SHEDS program promises power conversion efficiency improvements in future fiber laser pumps

Diode Laser CY’06 TAMs

  • $3.5B diode laser market is 59% of total laser sales

Industrial, Medical, Graphics and Other - $300M

Telecom/Datacom - $1.2B

Optical storage - $1.9B

Industrial diode market segmentation
Industrial Diode Market Segmentation

High-quality, telecom-grade diodes enable wholesale shift of industrial laser industry to diode-based solutions


Graphic Arts $32M

Displacement of classic lasers by Direct Diode systems



Diode TAM

Medical Diodes $75M

Displacement of classic lamp-pumped SSL and gas lasers by DPSSL

“Fiber Laser Market set to grow at a 35% CAGR through 2010” – Strategies Unlimited, Apr’06

Solid-State and Fiber Laser Pumps $160M


Diodes and fiber disrupting the laser industry


Diodes and Fiber – Disrupting the Laser Industry

  • Fiber is a new paradigm

    • Fiber-based Laser SS/Gas Lasers

    • Modular, spliced Delicate alignments

    • Service free Disposables

    • High efficiency (25+%) Low efficiency (few to 10%)

    • High brightness Inferior brightness

  • Direct Diode systems are just another fiber laser

  • Solid-state (classic) lasers are adopting fiber

spliced fiber


  • Pump diode lasers are mature, reliable

    • Telecom-grade diodes soon to be ubiquitous in the industrial laser industry

  • Fiber lasers are merely the most important variety of fiber laser
