1. A laser device comprising:
a signal generator configured to separately generate two or more of (i) a pulsed-wave signal, (ii) a quasi-pulsed-wave signal, (iii) a continuous-wave signal, or (iv) a quasi-continuous-wave signal for transmission as a laser control signal;
a laser source configured to receive the laser control signal and emit a laser beam responsive to receiving the laser control signal and in accordance with the laser control signal, wherein the laser beam comprises (i) a pulsed-wave laser beam, (ii) a quasi-pulsed-wave laser beam, (iii) a continuous-wave laser beam, or (iv) a quasi-continuous-wave laser beam;
another laser source configured to receive the laser control signal and emit another laser beam responsive to receiving the laser control signal and in accordance with the laser control signal, wherein the other laser beam comprises (i) a pulsed-wave laser beam, (ii) a quasi-pulsed-wave laser beam, (iii) a continuous-wave laser beam, or (iv) a quasi-continuous-wave laser beam;
a selective turning mirror configured to transmit the laser beam and reflect the other laser beam;
a turning mirror configured to reflect the laser beam and reflect the other laser beam;
an RFID reader configured to read from and write to an RFID tag embedded within an optical waveguide, wherein the RFID tag comprises a unique identifier associated with the optical waveguide, and the optical waveguide is configured to emit the laser beam from a second end of the optical waveguide after receiving the laser beam at a first end of the optical waveguide; and
control circuitry configured to:
receive a user request to operate in a requested mode comprising (i) a pulsed-wave mode, (ii) a quasi-pulsed-wave mode, (iii) a continuous-wave mode, or (iv) a quasi-continuous-wave mode;
responsive to receiving the user request, cause the signal generator to generate the laser control signal in accordance with the requested mode;
cause the RFID reader to read the unique identifier from the RFID tag;
identify the optical waveguide based on the unique identifier; and
write a use identifier to the RFID tag, wherein the use identifier indicates that the optical waveguide has been used in a surgical procedure;
wherein the selective turning mirror and the turning mirror are positioned relative to the laser source, the other laser source, and a first end of an optical waveguide such that (i) the laser beam is received at the first end of the optical waveguide after the laser beam is transmitted through the selective turning mirror and then reflected off the turning mirror, (ii) the other laser beam is received at the first end of the optical waveguide after the laser beam is reflected off the selective turning mirror and then reflected off the turning mirror, and (iii) the laser beam and the other laser beam are concurrently received at the first end of the optical waveguide as a multiplexed laser beam comprising the laser beam and the other laser beam.
