Fibre cleavers produce a clean break
Laser Components' fibre cleavers are designed for fibres with diameters from 80 to 200um and are well suited for the separation of polarisation-maintaining fibres
Laser Components has sold DPM (diode-pumped microchip) modules for several years. The modules comprise a 0.5mm thick Nd:YVO4 crystal that functions as a laser rod joined to 2mm thick KTP doubling crystals. With such a compact structure a frequency-doubled green laser beam of 532nm can be very easily generated by pumping with an 808nm laser diode.
The modules are available with various apertures and in low power and high power versions.
At 532nm, the output power of low power designs can reach up to 10mW and the output power of high power designs can exceed 60mW.
In addition to existing types with standard doping of 3%, Nd:YVO4 with 4% are now also available.
This results in a lower pumping threshold and, at the same pumping power, an increased output power.
DPM modules with Nd:GdVO4 laser rods have also been developed.
When compared with the Nd:YVO4 laser rods, the following differences can be observed: higher conversion efficiency; improved temperature stability; greater output power; lower lasing threshold; high absorption coefficients for the pump wavelength; large cross section for the stimulated laser emission; and good thermal conductivity.
In the near future, Nd:GdVO4 could replace the commonly used Nd:YVO4 in numerous applications.
