Diode Pumped Solid State Lasers from Continuum
New developments in DPSS
Continuum Confidential
The DPSS Line at Continuum
Nd:YLF
Nd:YAG
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
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
