A Broad Approach to Product Quality: – Exacting Production Protocols

• Expanded Cleanroom Facilities • Exacting Standardization/Spec Testing

– Engineered Hardiness

• “Shake and Bake” Testing

– Lasting Reliability • V2 Diode Modules • Consistent Performance

DPSS/Ultrafast Production Lab

• Class 10,000 clean room designed exclusively for DPSS and Ultrafast production – Daily particle tracking, 5S adherence and maintenance – Chillers and test equipment dedicated at each workstation for

individual system quality assurance

DPSS Line Engineering Testing

• All DPSS (Terra and Mesa) products qualified • Vibration/Shock/Drop tests performed

Drop testing 8” drop/container edge

Vibration testing X-Y-Z Axes, 5-200 Hz @30 min/Axis

Shock testing X-Y Axes, 100 10-g shocks/Axis

DPSS Line Engineering Testing

Iterative testing until every specification is reproduced

Mesa M2 before testing: <1.2

Mesa M2 after testing: <1.2 Power specification before/after testing

DPSS Line Engineering Testing

Minimum: 16.46 W Maximum: 16.74 W Average: 16.59 W Std dev: 0.03810 W %rms: 0.23 P-P %: 1.69

Long term power stability graph over 20 hrs after all tests completed: Mesa 532-16-0

DPSS Line Quality Assurance

• Each DPSS head Continuum produces is qualified for output performance and reliability – Repeated vibration testing

• Production laser meets specification Vibration 1 hour • All specifications tested again for consistency

– Full characterization of output beam: Power, M2, Pulsewidth

Continuum DPSS Advantages

• Maximum output efficiency due to intracavity doubling mechanism

• Proprietary diode module/pump chamber design ensures optimal output and ease of service – Peak performance maintained as diodes age – 3 minute diode module change on replacement – No cavity realignment needed after module swap

• User-defined repetition rate optimization • Hermetically purged/sealed optical cavity

DPSS Reliability: A Complete Package

• >60 Continuum DPSS units in the field

• Both Terra and Mesa lasers continue shipments throughout the world with optimal customer satisfaction
