…pulse duration, the follicle cells are
killed without causing thermal damage
to the dermis. This translates into an
optimum pulse width between ten and
hundred milliseconds, which is very
simple to achieve with the fast on/off capabilities of diode lasers.
…(DPSS) lasers with nanosecond pulse widths, CO2 lasers, or fibre lasers. These technologies are available at a reasonable cost and they support fast process throughput rates. Recently, a new class of so-called "high value" marking applications has emerged that require industrial picosecond lasers to…

…old as the laser itself. Originally, these cutting applications were dominated by multikilowatt, flowing gas CO 2 lasers. Over the past few years, higher-power (up to 1 kW) sealed, slab discharge CO 2 lasers have taken some of this market; this is because their short-rise-time pulses increase their…

Lasers process a wide range of materials in an extraordinarily diverse array of applications that often share a common requirement: the need to regularly measure laser output characteristics such as average power, pulse energy, pulse shape or beam profile to ensure…
…this laser principle is that the laser gas neither
needs to be circulated nor to be renewed
permanently. That means that turbines and
blowers susceptible to deterioration and
service are eliminated. Thus, optics integrated into the resonator that are contaminated by flowing laser…
Sealed CO2 Laser Coherent's Diamond Cx-10 Series sealed CO2 lasers are the best power-size ratio available in the market. Built on the highly acclaimed C-series platform, the Cx-10 utilizes a new state-of-the-art integrated RF power supply and a sealed waveguide design. This easy-to-integrate laser…
using shorter pulses (e.g., 30 ms or less) and longer wavelengths, hair removal is successful on darker skin types.
Coherent provides diode lasers at both 808 nm and 1060 nm,
as well as 760 nm, for this purpose.
