Diode Pumped Solid State Lasers from Continuum New developments in DPSS Continuum Confidential

The DPSS Line at Continuum A Broad Approach to Product Quality: – Exacting Production Protocols • Expanded Cleanroom Facilities • Exacting Standardization/Spec Testing Nd:YLF – Engineered Hardiness • “Shake and Bake” Testing – Lasting Reliability • V2 Diode Modules • Consistent Performance Nd:YAG

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 Vibration testing 8” drop/container edge 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 M 2 before testing: <1.2 Power specification before/after testing Mesa M 2 after testing: <1.2

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, M 2 , Pulsewidth In-house vibration table

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
