However, some studies show that treatment may be possible with a Q-switched alexandrite ( 755 nm ) laser.

However all such devices are classified as " lasers " based on their method of producing that light: stimulated emission.

However some high power lasers may be multimode, with the transverse modes often approximated using Hermite-Gaussian or Laguerre-Gaussian functions.

( However the term is not applied to mode-locked lasers, where the intention is to create very short pulses at the rate of the round-trip time ).

However, Ytterbium doped fiber lasers and amplifiers, operating near 1 micrometre wavelength, have many applications in industrial processing of materials, as these devices can be made with extremely high output power ( tens of kilowatts ).

However, many physical systems ( for example lasers ) are inherently " complex systems " in terms of the definition above, and engineering practice must now include elements of complex systems research.

However, since most lasers are monochromatic, color filters can reduce the effect of laser pointers.

However, many official chronological Star Wars sources state that blaster technology is different from real lasers.

However using lasers raises several issues:

However, typically, the term " terahertz " is used more often in marketing in relation to generation and detection with pulsed lasers, as in terahertz time domain spectroscopy, while the term " submillimeter " is used for generation and detection with microwave technology, such as harmonic multiplication.

However other visible as well as infrared lasing wavelengths are possible, and by using mirror coatings with their peak reflectance at these other wavelengths, HeNe lasers could be engineered to employ those transitions ; this includes visible lasers appearing red, orange, yellow, and green.

However in high power HeNe lasers having a particularly long cavity, superluminescence at 3. 39 μm can become a nuisance, robbing power from the lasing medium, often requiring additional suppression.

However, a relatively low cross-section of collision can be obtained in this manner, and the repetition rate of the lasers is limited to a few hertz rather than the megahertz repetition rates naturally arising in normal storage ring emission.

However, as yet, VCSELs have lower emission power compared to edge-emitting lasers.

However, with an appropriate design, titanium-sapphire can also be used in continuous wave lasers with extremely narrow linewidths tunable over a wide range.

However, laser guide star systems were under development at most major telescopes, with the William Herschel Telescope, Very Large Telescope and Gemini North having tested lasers on the sky but not yet achieved regular operations.

However, Demona can be injured by conventional bullets, bladed weapons, or more advanced weaponry, such as lasers, just as easily as a human can.

However, since the claimed-power of " laser pointer " products also includes the IR power ( in DPSS technology only ) still present in the beam ( for reasons discussed below ), comparisons on the basis of strictly visual-blue component from DPSS-type lasers remain problematic, and the information is often not available.

However, a few higher-powered ( 120 mW ) 404 – 405 nm " violet " laser pointers have become available which are not based on GaN, but also use DPSS frequency-doubler technology starting from 1 watt 808 nm gallium arsenide infrared diode lasers being directly doubled, without a longer-wave neodymium laser interposed between diode laser and doubler-crystal.

( However, as long as the heat transfer requirements are met, Solid State lasers may run continuously.

However, for convenience we will stick to the idea that information can be classified according to Table 1.

However, the surface temperature gradient can produce erroneous vapor-pressure measurements for the bulk liquid helium unless precautions are taken to isolate the tube ( which passes through the surface to the vapor pressure bulb ) from the liquid helium surface.

However, the healthy inventory position of the textile industry lends support to the broadly expressed belief that improvement in that industry can be expected by the second half of 1961.

However, it is essential that the various mathematical symbols used in the equations be understood so that the mathematical processes can be done properly and in their correct order.

However, the displacement of the cylinder can be converted to cubic centimeters.

However, the formation of organically bound iodine, mainly mono-iodotyrosine, can be accomplished in cell-free systems.

However, the leveling operation can be maintained and controlled remotely with no mechanical or optical contact with the platform.

However, this difficulty is not too serious if it is realized that a surveying team can establish a true north base line with a few days' work.

However, the teacher can only go so far if the attitude of the community and the family is anti-intellectual.

However, one can argue that no such control is necessary as long as one pretends that the anti-trust laws are effective and rational.

However much we may have to criticize liberal theology's constructive formulations, the theology we ourselves must strive to formulate can only go beyond liberalism, not behind it.

However, many consequences of treatment-unit additivity can be falsified.

However, certain critical interlocutory court orders, such as the denial of a request for an interim injunction, or an order holding a person in contempt of court, can be appealed immediately although the case may otherwise not have been fully disposed of.

However, no direct connection can be demonstrated, and the similarity of the abaci may be coincidental, both ultimately arising from counting with five fingers per hand.

However, such apparent simplifications can perversely make a script more complicated.

However, the opposite can also be true-An opponent can turn a positive statement into a bad one, if the speaker uses ambiguity ( intentionally or not ).

However, many DSCs, and also go-to systems, can work in conjunction with laptop sky programs.

However, it was held by the Supreme Court that an affidavit can be used as an evidence only if the Court so orders for sufficient reasons.

However, non-arable land can sometimes be converted into arable land.

However, anxiety should not be confused with fear, it is more of a dreaded feeling about something which appears intimidating and can overcome an individual.

However a comparable performing digital system is more complex and can require more bandwidth than its analog counterpart.

However, in digital systems, degradation can not only be detected but corrected as well.

However, the algorithm can be improved by adopting the method of the assumed mean.

However, some alloys can also have their properties altered by heat treatment.
