The laser generates pulses at a wavelength of 1.535 µm with 100 kW peak power and a pulse duration of 4 ns. Typical repetition rate is 10 Hz, but the laser may be operated at kHz rates for a few pulses.
Laser Quantum offers three diode-pumped solid state (DPSS) lasers with a range of output wavelengths designed for laser lithography applications. The gem series is available with 473, 532 and 660 nm output options.
By using a combination of hermetic sealing and an active fast feedback system, the gem can achieve outstanding levels of power and stability in all output beam characteristics. All three systems have a single traverse mode and their small, compact footprint makes them easy to integrate into larger platforms.
Hot electron relaxation and transport in nanostructures involves a multitude of ultrafast processes relevant for applications in photocatalysis and optoelectronics. Researchers employ time-resolved photoemission electron microscopy (Tr-PEEM) using the PHAROS laser from Light Conversion to image the relaxation of photogenerated hot electrons within InAs nanowires on a femtosecond time scale.
A unique light source is required to provide the high pulling rates of materials with very high melting points for processes such as Laser Heated Pedestal Growth (LHPG).
Color centers are of high interest in quantum technologies as single-photon sources or spin qubits. Researchers from Australia and Japan have applied PHAROS femtosecond (fs) lasers to generate vacancy-related color centers. The work highlights the simplicity and flexibility of laser writing of color center arrays.
The PHAROS laser from Light Conversion is an fs laser system combining mJ pulse energies and high average powers. PHAROS features a mechanical and optical design optimized for industrial applications.
These prisms can be glued or optically contacted for more high power applications. Unlike polarizing filters which absorb, cube polarizers are filters that reflect S-waves at 45° and transmit P-waves through the assembly.
An optical homogenizer is an optical component that makes the intensity profile of a light beam more uniform.
There are two groups of homogenizers:

The basic and most distinct advantage of a diffractive optical lens is its dimensions: simply being flat, thin and easy to integrate is in many cases enough to “seal the deal.”
Take a diffractive axicon (left lens in the image above), as opposed to its refractive, thick, bulky, pyramid-like counterpart (right lens in the image above). There is no doubt that the diffractive option is the easier one to use.
The use of diffractive optical elements (DOEs) in aesthetic laser treatments is well established in procedures such as fractional skin treatment and tattoo removal.
Such diffractive elements from Holo/Or can be tailored to any pair of wavelengths – treatment at wavelengths 1064 nm, 1550 nm, 2940 nm, or any other, and guide lasers at any visible wavelength.
