MLR10K-LX

High Performance Laser Rangefinders

Integration into larger assemblies such as handheld systems, gimbals, masts, or UAVs is simplified with its small size and ample mounting features.

Nd:YAG

Laser Materials

The first operation of yttrium aluminum garnet doped with tri-valent Neodymium as a laser gain media was demonstrated at Bell Labs in 1964 [1]. Today, Nd:YAG has achieved a position of dominance among solid-state laser materials, being the most widely used lasing medium world-wide, with applications spanning medical, industrial, military and scientific markets. Nd:YAG lasers typically emit infrared light at 1064nm - however other transitions near 940, 1120, 1320, and 1440 nm are also used [2].

TGG

Laser Materials

Terbium Gallium Garnet (TGG) is an excellent magneto-optical crystal used for optical isolator and rotator devices in the range of 400nm-1100nm, excluding 470-500nm. TGG has a high Verdet constant resulting in the Faraday effect making it most suitable for Faraday devices.

Advantages include:

• High Verdet Constant (35 Rad T⁻¹ m⁻¹)
• Thermal Conductivity (7.4W m⁻¹ K⁻¹)
• Low optical losses (<0.1%/cm)

Tm:YAG

Laser Materials

Tm:YAG is used as an efficient means to generate high power 2.01 micron laser emission from the ³F₄ - ³H₆ transition, for surgical cutting and coagulation applications due to the high water absorption at this wavelength [1]. Diode pumping is commonly employed into the 785nm ³H₆-³H₄ absorption feature. Of interest in Tm³⁺ activated systems is the increased quantum efficiency obtained thru Tm-Tm ion cross relaxation; a non-radiative process where an excited Thulium in the ³H₄ state (energy level around 12900 cm −1 ) decays to the ³F₄ state (energy level around 6000 cm −1 ) and a nearest neighbor ground-state Thulium ion is promoted to the ³F₄ level, along with phonon byproduct to satisfy energy conservation [2]. Thus, in appropriate concentrations, a single Thulium ion excited to the ³H₄ level generates two Thulium ions in the ³F₄ upper laser level.

Tm:YAP

Laser Materials

Teledyne FLIR Laser Crystals and Components offers high quality Yttrium Orthoaluminate, also referred to as yttrium aluminum perovskite (YAP), doped with Tm, Nd, Pr, Er and Cr.

YAP´s hardness and thermal conductivity are similar to YAG, but exhibits a highly anisotropic thermal expansion coefficient and is birefringent. YAP is an orthorhombic negative biaxial crystal belonging to the D162h (Pnma) space group. Emission wavelengths are polarized, and emission and absorption cross sections are dependent upon the crystallographic orientation. Teledyne FLIR Laser Crystals and Components (along with references [1] and [3] below), use the Pnma space group convention for defining the crystallographic a, b, and c-axis lattice constants. Others (including reference [2]) use the Pbnm convention. In the table below, we related the two conventions thru their common lattice constants.

Yb:LuAG

Laser Materials

LuAG (Lutetium Aluminum Garnet) is of particular interest as a material for diode pumped solid-state lasers employing active ions such as Yb, Tm, Er, and Ho. This host has the smallest lattice constant of the rare earth garnets and the resulting crystal field in LuAG yields narrower linewidths and higher absorption and emission cross-sections. The net effect is higher efficiency laser devices.

Yb:YAG

Laser Materials

Crystals doped with trivalent ytterbium (Yb³⁺) have demonstrated significant potential for application in compact, efficient, diode-pumped laser systems.[1-4] The Yb³⁺ ion has only two manifolds, the ground ²F₇⸝₂ and the excited ²F₅⸝₂ which are separated by approximately 10,000 cm⁻¹. As a result, Yb³⁺ doped materials have spectroscopic and laser properties that are advantageous for high energy 1 μm laser systems. In particular, Yb³⁺ doped materials should not suffer from concentration quenching, upconversion, or excited state absorption. The Yb³⁺ion also has a long energy storage lifetime (typically three to four times that of Nd³⁺ in the same host) and a very small quantum defect which reduces heat generation during lasing.

YSO

Laser Materials

YSO (Yttrium Orthosilicate) is a monoclinic biaxial crystal belonging to the C2/c (C6 2h) space group. Rare earth ions substitute for the Y³⁺ ions which occupy two crystallographic sites of C1 symmetry. Emission and absorption spectra for rare earth dopants are polarized and generally have higher cross-sections when compared to YAG.
Crystals of Y₂SiO₅ are available with a variety of dopant ions including Ce, Pr, Nd, Eu, Tb, Ho, Er, Tm, Tm:Ho, Ce and Cr.
Eu³⁺ and Er³⁺ activated YSO exhibit very narrow homogeneously broadened absorption line widths (sub kHz), embedded within a broader (–GHz) inhomogeneously broadened line, when cooled to cryogenic temperatures. Er³⁺:YSO was shown to have a homogeneous optical resonance width of only 73 Hz, the narrowest atomic resonance observed in any solid state material[1].
