Greencisco pulsed fiber semiconductor laser power supply is our company's latest developed laser power supply for pulsed fiber semiconductor lasers. This power supply integrates numerous advantages into one machine. A pulsed laser refers to a laser that can operate in either continuous or pulsed modes. When the rate of optical pulses is less than the cavity lifetime of the laser, it is called a pulsed laser. Some working media cannot withstand continuous pumping, so they can only operate in pulsed mode. When the laser operates in pulsed mode, it releases a huge amount of energy instantly, causing localized evaporation of metal materials and thus completing tasks such as drilling and cutting.
The generation of pulses primarily involves three methods:
1. Q-Switching Method
The Q-switch creates a Q cavity, where the pumping energy approaches the working level. It rapidly removes the introduced loss mechanisms (typically electrical or acousto-optic components), resulting in the instantaneous release of stored energy in the gain medium and producing high peak power.
2. Mode Locking Method
A mode-locked laser emits extremely short pulses sequentially within a timeframe ranging from tens of picoseconds to less than 10 femtoseconds. These pulses must complete a round trip between the mirrors of the resonator. Due to the Fourier limit (also known as the energy-time uncertainty), the pulse duration results in significant spectral broadening. Consequently, the gain medium must have a sufficiently wide bandwidth to accommodate the gain over these frequency. An example of a suitable material is synthetic titanium-doped sapphire (Ti:sapphire), which offers an extensive gain bandwidth, enabling the generation of pulses lasting only a few femtoseconds. Such mode-locked lasers serve as versatile tools in scientific research, maximizing the effects of nonlinear optical materials (e.g., generating second harmonics, studying processes occurring on ultra-short timescales such as femtosecond physics, femtosecond chemistry, and ultrafast science, as well as frequency down-conversion and optical parametric oscillators)
3. Pulsed Pumping Method
Another method for achieving pulsed laser operation is to use a pulsed pump source, such as a flash lamp or another pulsed laser. Historically, dye lasers used dye molecules with very short lifetimes for particle inversion, requiring high-energy, fast pulsed pumping. When using flash lamps, large capacitors are typically employed to generate intense flashes. Examples of such lasers include excimer lasers and copper vapor lasers. These lasers cannot operate in continuous mode.
