Clinical applications of Q-switched NdYAG laser.
682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...
متن کاملPassively Q-switched diode-pumped Cr:YAG/Nd:GdVO4 monolithic microchip laser
the realization of high repetition rate passively Q-switched monolithic microlaser is a challenge since a decade. To achieve this goal, we report here on the first passively Q-switched diode-pumped microchip laser based on the association of a Nd:GdVO4 crystal and a Cr:YAG saturable absorber. The monolithic design consists of 1 mm long 1% doped Nd:GdVO4 optically contacted on a 0.4 mm long Cr:Y...
متن کاملDiode edge-pumped passively Q-switched microchip laser
There is an increasing demand for high-intensity subnanosecond lasers for emerging industrial applications. While femtosecond and picosecond laser sources are considered promising, they suffer from the significant drawbacks of increased complexity and cost. In this regard, we demonstrate a unique edge-pumped passively Q-switched Nd∶YAG∕Cr4þ∶YAG microchip laser. The microchip is made of a Nd∶YAG...
متن کاملPassively Q-Switched Microchip Lasers Enable Ultrashort Pulses
high-peak-power subnanosecond pulses. No need for cumbersome high-voltage controllers or even a water cooling system. Passively Q-switched microchip technology for industrial lasers covers the range of hundreds of picoseconds down to 300 ps in the offerings of Teem Photonics. Peak powers in excess of 200 kW are readily available at 1 kHz using PowerChip microchip cavities, and a 50-kHz repetiti...
متن کامل2 MHz repetition rate , 200 ps pulse duration from a monolithic , passively Q - switched microchip laser
We present a monolithic passively Q-switched microchip laser generating 200 ps pulses at a wavelength of 1064 nm with a repetition rate of up to 2 MHz. While maintaining transversal and longitudinal single-mode operation, the pulse energy can be changed from 130 nJ to 400 nJ by varying the pump conditions of the laser. To the best of our knowledge, the repetition rate of 2 MHz is by far the hig...
