Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

Smaller, faster, and Matter-compatible, this sleek new lock is a worthy August replacement — with a few quirks.

Mamyshev oscillators (MOs) can emit high energy pulses using a laser generation technique known as harmonic mode-locking (HML). While MO employing HML has several advanced applications in varied ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

Do home hair removal lasers work? I tried two popular options, the Ulike Air 10 and Nood Flasher 2.0 for two months. Find out ...

We developed a real-time spectroscopy system for continuous measurement using a Fourier-domain mode-locked (FDML) laser. The FDML laser was driven at a sweep rate of 50 kHz in the near-infrared region ...

Mag-Snap Aimbot — millisecond target lock on head, torso, or limbs. Humanized Curve — customizable smoothing to mimic pro-league flicks. Color-Shift ESP — outlines hostiles, loot, traps, and team for ...

We propose and demonstrate a 250-GHz high-repetition-rate mode-locked Er-doped fiber laser, which utilizes a silicon micro-ring resonator (SMRR). The SMRR acts as an optical comb filter to help ...

The laser also features a long-cavity structure, which helps lower power consumption and achieve a less than one megahertz repetition frequency, making it suitable for a broad range of applications.

Through this strategy, they achieved a wide tunable range from 481 ps to 1.38 ns. This almost 1 ns tuning range is the largest ever reported for a narrow-bandwidth passively mode-locked laser.

Lasers have widespread applications as a light source in a variety of fields, including manufacturing, medicine, high-speed communications, electronics, and scientific research.
