PD-LD for Locked-On and Focused Diode Laser Excellence

A true diode laser alternative to time honored HeNe gas laser tubes is now available from PD-LD: the SLM-632.8 single longitudinal module.  The SLM-632.8 laser module beam quality and coherence length compares very favorably to traditional HeNe lasers from a compact, one-box design which is less than 90cm³ in volume.  The remarkable distinction between HeNe systems and the SLM-632.8 though, is the output power produced. This small form factor produces an output of 10x or more power, 40mW minimum, while consuming less than 7W.  Wavelength stabilization is also key to true single frequency performance.  PD-LD’s patented Volume Bragg Grating (VBG) technology ensures wavelength locked performance to 10MHz linewidths over a wide operating temperature range.  Power stability for the SLM is better than 0.2% over hours of use providing new application opportunities in a variety of industrial and scientific market segments.
