Q-Switch 120065-002 LEE LASER Overview
The LEE LASER 120065-002 is an acousto-optic Q-switch (AOQS) used as an optical modulation component inside industrial laser resonant cavities. Q-Switch 120065-002 LEE LASER controls optical loss via radio frequency (RF) signals to convert continuous laser energy into high-peak-power pulsed laser outputs.
Q-Switch 120065-002 LEE LASER Key Specifications & Operating Principle
RF Frequency:27.12 MHz (requires a matching 27.12 MHz RF driver).
Modulation: Applying the 27.12 MHz RF signal creates an internal acoustic diffraction grating that blocks the laser beam to store energy. Turning the RF signal off drops the cavity loss instantly, releasing a high-energy laser pulse.

Q-Switch 120065-002 LEE LASER FAQ
Q1: What is the primary function of the LEE LASER 120065-002 within a laser system?
A1: The LEE LASER 120065-002 serves as an intracavity acousto-optic Q-switch (AOQS). The purpose of the LEE LASER 120065-002 is to actively modulate the optical loss inside the laser resonant cavity, allowing it to compress continuous wave (CW) laser energy and release it as high-peak-power, high-repetition-rate pulsed laser beams.
Q2: What radio frequency (RF) is required to drive the Q-Switch 120065-002?
A2: The LEE LASER 120065-002 is engineered to operate at a fixed radio frequency of 27.12 MHz. To ensure proper acoustic wave generation and diffraction efficiency inside the crystal, the Acousto-optic Q-Switch must be paired with a dedicated 27.12 MHz RF driver.
Q3: Why does the LEE LASER 120065-002 require an active water-cooling system?
A3: The LEE LASER 120065-002 absorbs heat generated by both the internal RF transducer and the high-power laser beam passing through its crystal. Active water-cooling is mandatory for the Acousto-optic Q-Switch to stabilize its thermal profile, maintain optical alignment, and prevent catastrophic thermal cracking.
Q4: How does the over-temperature interlock protect the LEE LASER 120065-002 during a cooling failure?
A4: The LEE LASER 120065-002 relies on an integrated or loop-connected temperature monitoring system. If the cooling system fails and causes the temperature of the Acousto-optic Q-Switch to exceed safe operating limits, the interlock circuit instantly triggers a fault and automatically cuts off the 27.12 MHz RF power to shield the Acousto-optic Q-Switch from permanent thermal damage.
Q5: Is the LEE LASER 120065-002 still in active production by the manufacturer?
A5: No, the original manufacturer has discontinued this part. However, you can purchase the Acousto-optic Q-Switch directly from our spare center, where we maintain inventory for this specific model to support your ongoing equipment maintenance and replacement needs.
