Nd:YLF Laser Crystals and Components(for 1047nm&1053nm&1313nm&1370nm Laser)

Nd: YLF crystal is an important near infrared laser material. It can generate 1053, 1047, 1313, 1324 and 1370 nm wavelength lasers, and pump lasers with a wavelength of 755nm-811nm.It can be used as gain media for laser oscillators and preamplifier. Because it has better performance than Nd: YAG in single mode, high stability and so on, it can replace Nd: YAG crystal. It has the advantages of natural birefringence and long fluorescence life and has a very good development prospect.

At present, the cross-polarized low-temperature Nd:YLF laser emitting 1047nm and 1053nm simultaneously in a collinear resonator can be applied to fields such as holography, medical treatment or dual-wavelength lidar

Nd: YLF crystals are uniaxial crystals that can be used to emit lasers with wavelengths of 1047 nm and 1053 nm. These wavelengths correspond to πpolarization and σ polarization, respectively. So Nd: YLF crystal is a potential working medium producing orthogonal polarization at 1047 nm and 1053 nm at the same time. So it can be applied to self-perception measurements. In this kind of laser we need to realize the gain balance of simultaneous emission of orthogonal polarization with equal output power of two wavelengths. At present, the low temperature system is mainly used to produce Nd: YLF laser with high efficiency emitting at 1047 nm and 1053 nm simultaneously.

Ulticrystal Technology provides Nd:YLF crystals selected to have low inhomogeneity over the whole aperture. Crystals with a diameter of 10 mm, length of 120 mm and inhomogeneity of 0.1-0.3×10-5 are available.

Ulticrystal's Nd:YLF Crystal is featured by：

       •  High power, low beam divergence, efficient single mode operation.
       •  High average power Q-switching at a moderate repetition rate.
       •  Linear polarized resonators for Q-switching and frequency doubling.
       •  Potential uniform mode for large diameter rods or slabs.
       •  Stimulated emission cross section is favorable for low CW threshold.
       •  Thermal lensing lower than that of YAG.
       •  1053nm output of Nd:YLF matches gain curves of Nd:Glass and performs well as an oscillator and pre-amplifier for this host.
       •  Large diameter round rod or large size lath can also obtain uniform mode laser outpu.
