High peak power picosecond DPSS laser beam at 1064 nm causes Second Harmonics Generation in crystal quartz (video).
In the video below you can see how a high power laser beam (around 50MW), emitted by Passat’s picosecond DPSS laser at 1064 nm, caused rather strong excitation of green light in a quartz crystal. A similar phenomenon of frequency doubling in crystal quartz was discovered for the first time in 1961 using a ruby laser. For 1064 nm, [...][...]read more
Compiler HPRR model The brand new High Pulse Repetition Rate picoseconds DPSS Laser Compiler HPRR is a 10-kHz picosecond laser. This is the most advanced version among the Compiler family lasers. This model could be used for many applications, especially for wafer cutting, micro- and nano machining, semiconductors scribing, remote sensing. See details here…[...]read more
The deep UV laser is suitable for life science industries (biophysics, pharmaceuticals, bioengineering) as a stable laser source for Raman spectroscopy https://www.photonics.com/Article.aspx?AID=61543. The main advantages of the 213nm laser for Raman Spectrometry: · Increased sensitivity can result from UV excitation, since even non-resonance Raman scattering efficiency is proportional to λ-4, where λ is the laser [...][...]read more
Drilling holes in metal strips using diode-pumped solid-state picosecond laser Compiler HPRR. As you can see in the video, the drilling time is proportional to the drilling depth: Compiler HPRR is a 14-kHz picosecond laser. This is the most advanced version among the Compiler family lasers. This model could be used for many applications, especially [...][...]read more
