Abstract
The present invention relates to rare earth composition of aluminum boron silicate glass, particularly relate to be suitable as the glass based on aluminoborosilicate of solid laser medium.Especially, the wide transmitted bandwidth of these laser glasses based on aluminoborosilicate display rare earth lasing ion.Although being not entirely understood, but think that the broadening of described transmitted bandwidth realizes by there is substantial amounts of lanthanide ion in glass matrix.Further, since high Young's modulus, fracture toughness and hardness number, it is also suitable for transparent armor window material according to the rare earth aluminium borosilicate glass system of the present invention.
Description
Technical field
The present invention relates to use glass based on aluminoborosilicate as solid laser medium.Especially, the present invention relates to
The transmitted bandwidth of the rare earth ion making to be used as lasing ion in glass composition based on aluminoborosilicate is broadening.Although no
Be entirely understood, but think described transmitted bandwidth broadening be by there is substantial amounts of lanthanide ion in glass matrix and
Realize.Further, since high Young's modulus, fracture toughness and hardness number, described rare earth aluminium borosilicate glass system is also fitted
Share and make transparent armor window material.
Background technology
By preparing laser glass, described rare earth by the rare earth doped host glass system with transmitting laser ability
Element such as neodymium and ytterbium.The laser ability of launching of these rear-earth-doped laser glasses is caused by light amplification, wherein passes through
The stimulated emission of excitation rare-earth element ion in glass and realize described light amplification.
It is known that phosphate laser glass is used as the main matrix of the Optical Maser System of high-average power and high peak energies.
See, for example Payne et al. (US 5,663,972), it discloses the phosphoric acid being described as having the wide Nd doping of broad emission band
The purposes of salt laser glass.Hayden et al. (US 5,526,369) also discloses the phosphate laser glass of Nd doping.At this
In the case of Zhong, it is said that described laser glass has narrow transmitted bandwidth (less than 26nm) ideally to improve extraction efficiency.This
In the laser instrument of typical types, compared with transmitted bandwidth, the transmitting of typical laser is narrower, thus outside described narrow bandwidth
Wavelength (laser instrument works at that wavelength) place launches light and is actually wasted.For this reason it would be desirable to narrow transmitted bandwidth.
A kind of general trend of solid-state laser is to make high-energy laser have shorter pulse width, and it makes in pulse
Power reaches the highest numerical value.Such as, having the 10 of 10 Nanosecond Pulse Widths, the power of 000 joule of laser instrument is 1TW (1TW
=10000J/10 nanosecond).But, for using the high-peak power laser of extremely short pulse (< 100 femtosecond pulse or shorter)
For, known phosphate laser glass the transmitted bandwidth provided is too narrow compared with required transmitted bandwidth.In order to solve this
Individual problem, uses so-called " mixing " laser glass laser instrument to design.It is used in series phosphate glass and silicate glass with reality
The now current total bandwidth clapped needed for watt Optical Maser System.But, use the technology of hybrid glass for Chinese mugwort watt laser instrument in the future
System is inadequate.In the case of being with or without the silicate glass being used in series, will need to the phosphoric acid in new more broadband
Salt glass.
At " Terrawatt to pettawatt subpicosecond lasers ", M.D.Perry and G.Mourou,
Science, volume 264, describes the trend using the high-energy laser with relatively short pulse width in page 917~924 (1994).
These laser instrument use and are referred to as the technology of chirped pulse amplification (CPA) to produce extremely short laser pulse.In order to effectively work,
This technology requires the gain media with the biggest transmitted bandwidth.In Table 1, M.D.Perry and G.Mourou describes
The transmitted bandwidth of some typical Solid State Laser Systems and pulse width and theoretical peak.
Except phosphate glass, silicate, borate, borosilicate and aluminate are used also as the master for lasing ion
Glass matrix system.Compared with phosphate glass, silicate, borate, borosilicate and aluminate glass for Nd laser from
Son has broader transmitted bandwidth.
But, use these glass to be attended by disadvantageously.Such as, silicate glass is the most at very high temperatures
Fusing, unless it contains substantial amounts of modification body, such as alkali metal or alkaline-earth metal.On the other hand, borate glass has low temperature
Pre-arcing characterisitics, but its alkali metal needing at a relatively high concentration or alkaline-earth metal are to keep stable in environment around.Borosilicic acid
Salt glass can be at room temperature durable, and also melts at a temperature of similar with standard available glass, such as soda-lime glass.
But, typical commercially available borosilicate glass contains substantial amounts of alkali metal, and described alkali metal contributes to high boric acid in fusing
Salt volatility, is similar to phosphate glass.Aluminate glass shows the widest transmitted bandwidth, and grasps for short-pulse laser
Make attractive.But these glass have the highest crystallization tendency.
Known MgO-Al2O3-SiO2And MgO-Al2O3-B2O3Compositional system provides high Young's modulus value.But, two
Individual system is both needed to stand the highest fusion temperature, i.e. be not less than 1600 DEG C.It addition, MgO-Al2O3-SiO2System need to stand height
Crystalline rate.When by compositions from 1550 DEG C of coolings, only it is greater than 5 × 105DEG C/min quick cooldown rate
