Laser Systems Technology Team (TLS) The Laser Systems Technology team ( in french TSL: Technologie des Systèmes Lasers) has been in existence for more than 30 years under other names : Laser and applications, Gas lasers and Solide state lasers . The TLS team has always been interested in the lasers development aspect, which has enabled the team members to acquire unique know-how at the national level in the field of laser technologies. The team mainly has the following equipment: – CO2 laser marking system (CO2 laser, 9.6 μm, CW). – diode laser pumped solid laser (DPSS, 532 nm, QCW) – Nd: YAG laser+ OPO (1.57 μm, pulsed) – Nd: YAG laser + frequency doubler (532 nm, pulsed). – picosecond fiber laser (1030 nm). – Ruby laser oscillator (694.3 nm). – He-Ne lasers (632.8 nm, CW) for alignment. – Laser beam analyzer. Know-How and expertise The team members have developed expertise in laser technologies field such as: Flash lamps pumped solid state lasers. Gas lasers (slow-flow CO2 laser) Excitation systems for solid state lasers. Laser marking systems. Automation of laser systems.
