 It's a 589nm yellow laser. There are shading parts on the front of the laser flashlight. Before use, you need to open the shading sheet. The threaded metal part of the laser head expands the heat dissipation surface area, which is conducive to the long-term operation of the laser. The blue button is the switch button. There is a switch lock and a safety key at the rear of the laser. The power supply of the laser is an 18650 battery. This is the laser of TEM00 . Let's check it now. Installation introduction. 1. Install the battery first. An 18650 battery, with the positive pole facing the end of the laser. 2. Plug in the remote control switch and key, and the key rotates 90°. 3. Open the front shading part and turn it to the ON position. 4. Press the blue switch button. 5. Warm up for about 5 seconds, the laser starts to work. The real shot effect when the yellow laser spot is on the white baffle.

  All-solid -state yellow lasers pumped by laser diode are developing quickly, and have great applications in laser medical, space target detection and identification, spectrum, laser display and other fields. At present, allsolid -state yellow lasers at 589nm with high power, high stability, high efficiency and high beam quality are theresearch interest in laser field. The research status and development of all-solid-state yellow lasers at 589nm were summarized and analyzed in this paper, which was useful reference for the future research in this field. Nd:YAG uses Nd3+ as the activated particle, and its main transition energy level diagram and emission cross-section parameters are shown in Figure 1, and Table 1. The Nd3+ particles located at the energy level of the laser will undergo radiation transitions to the three terminal energy levels of 4F9/2, 4F11/2 and 4F13/2 at the emission branch ratio of 0.6:0.25:0.14, emitting 946nm, 1064nm and respectively. 1 319nm fluorescence s...

It's a 589nm yellow laser pen, and the laser power is 5mW. It use a CR2 3V battery. Install the battery with the positive terminal toward the tail. This pen is very portable.

This video is from CivilLaser, it's a yellow fiber coupled laser , the wavelength is 589nm,  the output power is 1W. This DPSS laser coupled with a FC/PC optical fiber. Let's check it now Fiber Core Diameter: 105μm /200μm /400μm /600μm /800μm /1000μm(Choose) Fiber Length：1m/2m/3m (Choose) Interface type: FC/PC, SMA905, FC/APC (Choose)

The Quantas DPSS , Nd:YAG or Nd:YLF, and tunable lasers provide low repetition rates of 0 to 100 Hz. Pulse energy of up to 100 mJ is available. The air-cooled systems supply harmonic generation down to the fifth harmonic (approximately 210 nm), and integrate OPOs and frequency shifts to cover a spectrum from 210 to 2600 nm.
