Which laser has highest frequency?

Which laser has highest frequency?

The wikipedia page for gamma-ray lasers certainly makes them sound like a difficult research project, not something in production. The graphic they have for commercial lasers by frequency seems to imply the highest-freq commercially available laser is pretty solidly ultraviolet.

Which of the laser has the highest power?

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or …

What does the frequency of a laser mean?

The optical frequency (for example of a quasi-monochromatic laser beam) is the oscillation frequency of the corresponding electromagnetic wave. The optical spectrum tells one how the power is distributed over the frequencies, i.e., it specifies the power spectral density as a function of frequency or vacuum wavelength.

How does frequency affect a laser?

The true measure of a laser is how well it can pack photons into a small area. However, it is also true (According to the photon energy formula E=hf ) that as you increase the frequency (decrease the wavelength) that the energy per photon will increase.

What is the typical Haz of a laser cutting machine?

An HAZ of 0.5 mm with continuous wave CO 2 lasers and 0.15 mm with pulsed CO 2 lasers is typical in 3 mm thick mild steel. Stiration-free cutting of thin sheets of metals can be possible fiber laser cutting ( Powell et al., 2011 ).

What are the disadvantages of laser cutting brittle materials?

Laser cutting of brittle materials such as ceramics, semiconductors and glasses overcomes the difficulties of mechanical machining in terms of tool wear and cutting speed. However, laser cutting of brittle materials can often result in undesirable micro-cracking, cut path deviation and undesirable heat effects such as recasts, spatter and debris.

Does laser cutting of Ti-6Al-4V alloy increase the stress levels?

Yilbas et al. (2011) studied laser cutting of holes in titanium alloys. The findings revealed that stress levels around the cut section increased for small hole diameters. In the present study, laser straight cutting of Ti-6Al-4V alloy is carried out.

What are the applications of lasers in everyday life?

Lasers are used in optical disk drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic and free-space optical communication, laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed,…
