Leaders in Light Perfect for Raman
Agenda Short corporate profile Advantages of the Starbright technology Our demanding quality assurance programme Overview of the Starbright lasers
Torsana Laser Technologies A/S Founded % owned by Juel Nielsen Holding A/S Based on a 50-year old tradition of consistent innovation
Leaders in Light Torsana Laser Technologies manufacture application- specific superior laser systems for photonic analysis instruments. Aiming at becoming the number one manufacturer in every application niche we move into and continuously explore new niches. The success of our customers is our success.
Perfect for Raman microscopy Starbright technology advantages: Ultra high spectral and spatial resolution enabled by excellent beam quality and line width Very high sensitivity due to effective repression of ASE Short acquisition time with high power Flawless stability in wavelength and power Claim ratio is less than 2 % on all end users since August 2005
Excellent spectral resolution enabled Courtecy of Jasco
Tapered diode Single mode diode with integrated amplifier structure Enbles combined advantages of single mode diode reliability and life time, with the high output power ensured by the integrated amplifier
Impeccable quality performance Claim ratio is less than 2 % on all end users Since August 2005
Quality assurance Carefully selected diode manufacturer, producing to our specifications. Rigorous testing and selection of diodes. Special cavity design and electronics ensures correct optical and electrical operating environment for the diode. This removes unwanted optical stress for the diode, which could have long term effects.
Quality assurance Highest precision specification measurement report for each laser including simulation of room temperature change. Strong destructive temperature cycling performed on each cavity to ensure long-term alignment stability. 300 hrs performance test on each laser before shipment.
Extensive testing procedures 1.A-test Verifying specification fulfilment, By monitoring stability of wavelength and power, plus single frequency operation, in changing external/ambient temperature conditions: 20 -> 30 -> Temperature stress cycling procdure with the diode turned off. Internal temperature of the laser is temperature is rapidly and strongly cycled up and down. 3.B-test Verifying long term alignment immobility of components. By ensuring performance is completely unchanged, after the temperature stress cycling procedure. Comparing test A and B. 4.Long term running, for 300 hours. 5.End test Verifying specification fulfilment again, The same way as the A-test. 6.Individual test report as above is shipped with each laser.
