    DPSS laser module 1064 nm (NIR) - principles, parameters.
    Diode-Pumped Solid-State (DPSS) lasers commonly use rare-earth-doped crystals like Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) and Nd:YVO4 (Neodymium-doped Yttrium Orthovanadate) as the gain medium. These crystals are typically pumped by an 808 nm laser diode to emit infrared light, usually at 1064 nm, which is then frequency-doubled for visible, such as green 532 nm, or UV output. 
    Common DPSS Laser Gain Media: 
    • Nd:YVO4 (Neodymium-doped Yttrium Orthovanadate): Often used in green laser pointers and compact modules. It provides high gain, low threshold, and strong absorption at the pump wavelength, making it highly efficient, especially for 1064 nm and 1342 nm outputs. 
    • Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet): Frequently used for high-power, industrial, and medical applications. It is known for good thermal conductivity and robustness. 
    • Nd:GdVO4 (Neodymium-doped Gadolinium Vanadate): A promising material that combines high absorption coefficients (like Nd:YVO4) with better thermal conductivity. 
    • Yb:YAG (Ytterbium-doped YAG): Utilized for high-power applications, operating typically around 1030 nm. 
    Key Components and Characteristics: 
    • Pump Source: Diode lasers provide the pump light, most commonly at 808 nm, to excite the gain medium. 
    • Frequency Conversion: Non-linear crystals, commonly KTP (
      KTiOPO4cap K cap T i cap O cap P cap O sub 4
      𝐾𝑇𝑖𝑂𝑃𝑂4
      ), are used to convert the infrared light (1064 nm) to visible light (532 nm) through a process like intracavity frequency doubling.       
    • Characteristics: DPSS lasers are favored for their high stability, efficiency, compact size, and high-quality beams, frequently replacing, for example, gas lasers, in laser marking, cutting, and laser pointers.

    What materials are used as a laser medium?
    Certain crystals, typically doped with rare-earth ions (e.g. neodymium, ytterbium, or erbium) or transition metal ions (titanium or chromium); most often yttrium aluminium garnet (Y3Al5O12), yttrium orthovanadate (YVO4), or sapphire (Al2O3); and not often caesium cadmium bromide (CsCdBr3) (solid-state lasers)
