Polarizing Optic─ Lateral Displacement Polarization BeamsplitterWaveplate Lateral Displacement Polarization BeamsplitterPolarizer Lateral displacement polarization Beamsplitter produces two parallel output beams which are separated by a lateral displacement. And the displacement is decided by the size of rhomboid prism. This Beamsplitter consists of one or two rhomboid prisms cemented to a right angle prism, and sometimes we can add a waveplate to manage the polarization state of the output beams. By using high precision prisms, we can ensure the parallelism between input and output beams within 30 arc seconds. And all entrances feature a multi layer anti-reflection coating. 2A A ADepolarizer Split incident beam into two displaced parallel beams Glue Waveplate can be added to manage polarization state NOA61 cemented RoHS CompliantBrewster Window Specifications BK7 ±0.2mm Quartz Polarization Material 60/40 scratch and digRotator Dimension Tolerance <1 arc minute Surface Quality Beam Deviation /[email protected] Transmitted Wavefront Distortion >100:1 for broadband;>500:1 for single wavelength Extinction Ratio Tp>90%, Ts<1% Transmission Rs>99%, Rp<5% Reflection R<0.25%@central wavelength on all entrances AR Coating >500mJ/cm2，20ns，20Hz@1064nm Damage ThresholdOptical Isolator Standard Product Part No. Material A(mm) Tp/Ts Wavelength(nm) Lateral Displacement LDP0112-4 12.7 >100:1 450-650Polarization Beamsplitter LDP0125-4 25.4 >100:1 450-650 LDP0112-6 12.7 >100:1 650-900 LDP0125-6 25.4 >100:1 650-900 LDP0112-9 12.7 >100:1 900-1200 LDP0125-9 25.4 >100:1 900-1200100 Tel:+86 27 87531505 Fax:+86 27 87531525 Email:[email protected] Http://www.u-optic.com

Crystal─Nd:Ce:YAGLaser Crystal Nd:Ce:YAGNonlinear Crystal Nd:Ce:YAG is an excellent laser material widely used for no-water cooling and miniature laser systems. In double doped Nd:Ce:YAG crystals Cerium are chosen as sensitizer for Nd3+ ions because of its strong absorption in UV spectral region at flash lamp pumping and efficient energy transfer to the Nd3+ excited state. As a result, thermal distortion in Nd: Ce:YAG is low and the output laser energy is greater than that in Nd:YAG at the same pumping. Therefore it is possible to realize high power lasers with good beam quality. Lasing wavelength at 1064 nm, laser damage threshold and thermal conductivity of the Nd: Ce:YAG crystals are the same as for Nd:YAG. It is the most ideal laser material for the air cooling lasers .It is suitable for different modes of operation (pulsed, Q- switched, mode locked) and high-average power lasers.

Crystal─E-O Crystal OverviewE-O Crystal Laser CrystalE-O Crystal Overview Nonlinear CrystalWhen an electric field (E) is applied to an electro-optic (E-O) crystal, the Passive Q-Switch Crystalrefractive index of E-O crystal will change linearly to electric field. Thephenomenon is called linear electro-optic effect. If a linearly polarized E-O Crystallight passes through an E-O crystal, the phase retardation (¢) will beinduced by (ne-no) to ¢= 2p(ne-no)L, where L is crystal length, for KD*P,again as an example, ¢ =pLno3r63E/l. It is clear that the phase of light willchange together with electric field (E). This is called electro-optic phasemodulation.If two crossed polarizers are placed at input and output ends of E-O crystal separately, the output intensity of light will be I =I0sin2(¢/2), where I0 is input intensity. That means the intensity or amplitude of light can also be modulated by electric field.This is called amplitude modulation.There are two kinds of E-O modulations. One is longitudinal E-O modulation if the directions of electric field and lightpropagation are the same. The KDP isomorphic crystals are normally used in this scheme. If the directions of electric fieldand light propagation are perpendicular, it is called transverse E-O modulation. The LiNbO3, MgO:LiNbO3, ZnO:LiNbO3, BBOand KTP crystals are usually employed in this scheme.The half-wave voltage (Vp) is defined as the voltage at ¢ = l, for example, Vp=l/(o3r63) for KD*P and Vp=ld/(2no3r22L) forLiNbO3, where l is light wavelength and d is the distance between the electrodes.BBO crystal is an excellent electro-optic crystal for high power applications at the wavelength range from 200nm to 2500nm.It has electro-optic coefficients g11=2.7pm/v, g22, g31<0.1g11. It can be used for Q-Switching a cw diode pumped Nd:YAG laserwith average power>50W.LiNbO3 is widely used as electro-optic modulator and Q-switch for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well asmodulator for fiber optics, etc. If the light propagates in z-axis and electric field applies to x-axis, the refractive retardation willbe G = pLnr22V/ld. The electro-optic coefficients of LiNbO3 are: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V at low frequencyand r33 = 31 pm/V, r31 = 8.6 pm/V, r22 = 3.4 pm/V at high electric frequency.KTP has promising E-O and dielectric properties comparable to those of LiNbO3, which makes it extremely useful to variousE-O devices. When these properties are combined with high damage threshold, low optical loss at high average power, wideoptical bandwidth, thermal and mechanical stability, KTP crystals are expected to replace LiNbO3 crystals as E-Omodulators, especially for mode-locking diode laser pumped Nd:YAG and Nd:YLF lasers as well as Ti:Sapphire andCr:LiSrAlF6 lasers. KTP crystal was successfully used to mode lock a diode laser pumped Nd:YLF laser at 270MHz withpulse width of 15 ps and spectral band width of 73 Ghz.The following Table gives the comparison of KTP and those commonly used E-O modulator materials.Material Phase Amplitude KTP e n r (pm/V) k (10-6/°C) n7r2/e(pm/V)2 r (pm/V) k (10-6/°C) n7r2/e(pm/V)2LiNbO3 15.4 1.80 KD*P 27.9 2.20 35.0 31 6130 27.0 11.7 3650 48.0 1.47 31.0 82 7410 20.1 42 3500 26.4 9 178 24.0 8 178 Birefringent CrystalKD*P crystal is widely applied for electro-optic application as Q-switch and Pockel cells.
