FLEXIBILITY WITH PRECISION is the tunable laser light source for continuous-wave (cw) emission in the visible and near-infrared wavelength range.

Thus, it allows you to tune from blue to red and into the near-infrared without any change of dyes or optical components. This makes a flexible and userfriendly laser for your applications.

2 FLEXIBILITY WITH PRECISION is the tunable laser light source for continuous-wave (cw) emission in the visible and near-infrared wavelength range. Its technology is based on optical parametric oscillation (OPO) and it is fully computer controlled. Thus, it allows you to tune from blue to red and into the near-infrared without any change of dyes or optical components. This makes a flexible and userfriendly laser for your applications. Change the way you work Visible, widely tunable, continuous-wave for a long time this was equivalent to the handling of toxic dyes, to changing laser media or resonator mirrors or the restriction to narrow tuning ranges. is a solid state system that has no consumable components such as dyes. The wavelength can be simply set at the computer. tunes itself automatically and guarantees superior beam quality as well as output stability across the whole tuning range offering both high flexibility and precision at the same time. It offers you single frequency operation, narrow spectral linewidth and options for frequency stabilization combined with an unprecedented spectral coverage. Focus on your research, not on laser handling: helps you free your mind for your main tasks. Precision and flexibility for demanding applications: Atomic physics Quantum optics Metrology Spectroscopy Biophotonics Photochemistry Holography Interferometry and much more! Operation Principle combines two nonlinear processes to achieve its outstanding spectral coverage: In the first step (OPO), a 532 nm laser pumps a nonlinear periodically-poled crystal. Signal and idler photons with tunable frequencies in the near-infrared wavelength regime from 900 nm to 1300 nm are generated. Subsequent second harmonic generation (SHG) using a frequency doubling crystal leads to conversion of the signal photons into colours from blue to green ( nm), while the idler photons get converted into colours from green to red ( nm). The modular design of enables you to choose the colour ranges that you require! Pump laser Signal SHG SHG OPO Idler
