- Page 4 1.1. Laser Safety Refer to pump laser safety and operating instructions prior to operating the dye laser. Elforlight dye lasers are designed and optimised to operate with FQS and SPOT lasers as manufactured by Elforlight. These Q-switched lasers have outputs at 532nm for dye laser pumping.
- Page 5 1.2. Dye laser operation The Elforlight dye laser is normally supplied with an Elforlight pump laser. The pump/dye laser combination will be pre-aligned in the factory and should need minimal alignment at installation. Prior to operation a dye solution will be required. See Appendix 1 for mixing dye solution procedure.
- Page 6 Tuning Filters: The dye laser is shipped with either one or two filters to cover the tuning range, depending on type of pump laser supplied. One extends up to 589nm, and the other above 589 to 610nm or further. The filter is held in its mount with an M2 set screw, which takes a 0.9mm wrench. Set screw Filter To change the filter, whilst wearing gloves or finger cots, loosen the set screw and...
- Page 7 1.3. Dye laser alignment Alignment procedure: Laser eye protection should be worn. If the laser has been factory aligned with the same type of laser with which it is to be utilized, then the alignment should consist of simply bringing the pump beam into the dye laser centrally along the cavity.
- Page 8 If the laser does not lase, try removing the tuning filter: it can be released by loosening the set screw in the top of the mount (0.7mm Allan key). Take great care not to touch the optical surfaces of the filter – wear finger cots. If the laser lases without the filter, peak up the alignment for maximum power then replace the filter, again with great care not to touch it.
- Page 9 Appendix 1 Dye Solution The test dye is Pyrromethene 597. A solution should be prepared with 40mg of dye in 30ml of Ethanol. The dye tubes should be connected between the dye pump and the dye cell. Turn on the dye pump and ensure there are no leaks in the system. Check that there are no air bubbles in the system.
- Page 10 Appendix 2 Notes on operation with variable rep rates The Elforlight dye laser pumped by a SPOT laser runs at repetition rates to 10kHz. The performance at higher rep rates degrades in terms of energy and beam quality due to inadequate exchange of dye molecules between pulses at higher repetition rates.
