The finesse pure has recently been upgraded to offer an even greater performance. Similar to the finesse, it contains PowerLoQ™ technology that ensures long term stability of the laser output to below 0.05% with typical values of 0.02%. With field replaceable diodes, pointing stability below 2 µrad/°C and the user optimisation capability, the finesse pure is an ideal laser for applications such as oscillator pumping.
