Cr:LiSAF Laser Crystal
We provide high-quality Cr: LiSAF (chromium doped aluminum strontium lithium fluoride Cr3 +: lisralf6, referred to as Cr: LiSAF), Cr: Licaf crystal (chromium doped calcium fluoroaluminate lithium crystal) and Cr: lisgaf. We also provide undoped LiSAF, lisgaf and Licaf crystals. These crystals are made of high-quality crystal growth materials and grown by Czochralski technology, The quality of crystal growth was monitored by absorption spectroscopy. Cr: LiSAF (chromium doped aluminum strontium lithium fluoride Cr3 +: lisralf6, abbreviated as Cr: LiSAF) crystal is a typical colquirite crystals, is a "vibronic" laser medium, which is widely tuned in the near-infrared band (~ 780 nm to 1010 nm) and can support ultrafast laser as short as tens of femtoseconds (the research surface shows that the crystal can produce pulses as short as 24 FS). Compared with titanium sapphire laser, The femtosecond laser made of this crystal has lower cost, because it can use the red band as the pump source instead of the green laser as the pump source, has a lower pump threshold, and can be directly pumped by semiconductor laser.
It is excellent laser material with high energy storage and high slope efficiency. It is also ideal working material under conditions of ultra short pulse and ultra high power. Currently, Cr:LiSAF related products such as flashlight pumping and diode pumping laser have been widely used.
