Crystals Grown for technical applications
 
Barium beta – Borate
  (b - BaB2O4 or BBO)

BBO having the unique combination of the major properties of nonlinear crystals are the best candidates for NLO application in the VUV (vacuum ultraviolet) and visible area. BBO is an efficient NLO crystal for the second, third and fourth harmonic generation of Nd:YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213nm. Our BBO are widely used in Tunable lasers: Dye lasers, Ultrafast Pulse lasers, Ti:Sapphire and Alexandrite lasers, Argon Ion and Copper-Vapor lasers. BBO's OPO and OPA are powerful tools for generating a widely tunable coherent radiation from the UV to IR.

Lithium Triborate
  (LiB3O5 or LBO) Due to the very high nonlinear optical properties , the LBO crystal is very suitable for harmonic generation of high-intencity laser radiation in vacuum ultraviolet and visible spectre. LBO allows to achieve the highly efficient SHG of nanosecond, picosecond, cw and diode laser pumped Nd:YAG and Nd:YLF lasers for R&D, medical, industrial and military applications. The superiority of LBO is proved for the SHG of Ti:Sapphire, Alexandrite and Cr:LiSAF laser radiation as well as for optical parametric amplifiers and oscillators pumped by Excimer lasers and harmonics of Nd:YAG lasers. To have a good transmission in the UV allows to obtain tunable UV and VUV radiation by SFG in LBO.

ADVANTAGES

-          Broad transparency range for UV-range (to .16 mm)
-          Type I and type II non-critical phase matching (NCPM) over a wide wavelength range

-          Relatively large effective SHG coefficient (about two times larger than that of KDP)

-          High damage threshold (> 10 GW/cm2 for 10 ns laser at 1.064 mm)

-          Wide acceptance angle and small walk-off

-          High optical homogeneity Dn 10-6/cm

 

APPLICATIONS

-          Intracavity harmonic generation of Nd:YVO4, Nd:YAG and Nd:YLF lasers with Diode pumped
-          Second harmonic and third generation of high power Nd:YAG and Nd:YLF lasers for scientific and industrial application

-          Optical parametric amplifiers (OPA) and oscillators (OPO) pumped by Excimer lasers and harmonics of Nd:YAG lasers

-          Frequency-doubling (SHG) and tripling (THG) of high powerful Nd:YAP laser at 1.34 mm

-          Second harmonic generation Ti:Al2O3, Cr:BeAl2O4, and Cr:LiSAF lasers

Potassium Titanyl Phosphate
   (KTiOPO4 or KTP)

KTP is the most suitable material for the visible and near UV NLO applications. KTP is commonly used for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, particularly when the power density is at a low or medium level. Extra- and intra-cavity frequency doubled Nd:lasers using KTP are preferred pumping source for visible dye lasers and tunable Ti:Sapphire lasers as well as their amplifiers; being also very usefull sources for many reseach and industry applications.

ADVANTAGES

-         Large nonlinear optical coefficient (6-13 pm/V)

-         Wide angular bandwidth (Lj = 13 mrad. cm, LDq = 75 mrad. cm for SHG

Type II at 1064 nm

-         Broad temperature bandwidth (LDT = 16 grad.cm for SHG Type II at 1064 nm)

-         Non hydroscopic, good chemical and mechanical properties

 

APPLICATIONS

      -         Frequency doubling of Nd:YAG , Nd:YVO4, and Nd:YLF lasers for red/green output

-         Frequency mixing (SFM) of Nd laser and diode laser for blue output

-         Parametric sources (OPG, OPA and OPO) for .6 mm-4.5 mm tunable output

-         Generation safe for eyes of 1.5-1.6 mm radiation widely used in range-fingering
