Fiber-coupled Industrial Diode Laser Eras

 Reliability (inception  2003) “$$$’s and *#&%^!!” – DPSS is considered

technology of the future

been, always will be…”) (“always has – 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?

 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…

 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

Third Industrial Diode Era - Efficiency

 Diode Efficiency (2005  ?) “still $/Watt” – reliable power is limited by waste heat

32 Watts 7

 For diodes to progress, efficiency must increase © 2006 JDSU. All rights reserved.

Diodes and Fiber – Disrupting the Laser Industry

 Fiber is a new paradigm – Fiber-based Laser – Modular, spliced – Service free – High efficiency (25 + %) – High brightness SS/Gas Lasers Delicate alignments Disposables Low efficiency (few to 10%) Inferior brightness

11

  Direct Diode systems are just another fiber laser Solid-state (classic) lasers are adopting fiber © 2006 JDSU. All rights reserved.

Summary



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
